Halo: The Flood

CHAPTER TEN

D+68:03:27 (SPARTAN-117 Mission Clock) /

Halo Control Room.

The vast platform that extended out over the Control Room’s black abyss felt small and confining as the Master Chief was attacked from every direction at once. Ruby red energy beams sizzled, and the smell of ozone filled the air as the airborne Sentinels circled, searching for a chink in his armor. All they needed was one good hit, a chance to put him down, and they would be able not only to take his head, but the Index as well.

Cortana’s intrusion skills had become much less conventional since the landing on Halo. He had been surprised when she’d used his suit comm as a de facto modem to broadcast her way into the Control Room computers. He was also unprepared for her sudden return. After so much time in the ring’s massive systems, she felt somehow larger. He pondered her unusual behavior—her shortness, the flare of temper.

There was no time to consider Cortana’s “mental state.” There was still a mission to achieve: protect Cortana, and keep Spark the hell away from the Index. For his part the Spartan wove back and forth, conscious of the fact that the walkway had no rails, and how easy it would be to fall off the edge.

That made hitting his targets a great deal more difficult. Still, he had seen the Flood bring Sentinels down, and figured that if the combat forms could do it, so could he. He decided to tackle the lowest machines first.

He was careful to get a good lead on each target. The assault rifle stuttered, and the nearest target exploded. He switched to the shotgun and fired methodically. He pumped a new round into the chamber, and fired again.

Thanks to the broad pattern provided by each shell, the pump gun soon proved itself to be an extremely effective weapon against the Sentinels.

One of the machines exploded, another hit the deck with a loud clang, and a third trailed smoke as it spiraled into the darkness below.

The battle became somewhat easier after that, as there was less and less incoming fire, and he was able to knock three more robots out of the air in quick succession.

He started to move, reloading as he went. One especially persistent machine took advantage of the interlude to score three hits on his back, which triggered the audible alarm, and pushed his shield to the very edge.

With only four shells in his weapon, the Chief turned, blew the robot out of the air, and spun to nail another. Then, weapon raised, he turned in a circle, searching for more targets. There weren’t any.

“So,” he said as he lowered the shotgun and pushed more shells into the receiver, “don’t tell me—let me guess. You have a plan.”

“Yes,” Cortana replied unabashedly, “I do. We can’t let the Monitor activate Halo. We have to stop him—we have to destroy Halo.”

The Spartan nodded and flexed his stiff shoulders. “And how do we do that?”

“According to my analysis of the available data I believe the best course of action is somewhat risky.”

Naturally, the Chief thought.

“An explosion of sufficient size,” Cortana explained, “will help destabilize the ring—and will cut through a number of primary systems. We need to trigger a detonation on a large scale, however. A starship’s fusion reactors going critical would do the job.

“I’m going to find out where the Pillar of Autumn went down. If the ship’s fusion reactors are still relatively intact, we can use them to destroy Halo.”

“Is that all ?” the Spartan inquired dryly. “Sounds like a walk in the park. By the way, it’s nice to have you back.”

“It’s nice to be back,” Cortana said, and he knew she meant it. Although there were any number of “natural” bio-sentients that she thought of as friends, the bond the AI shared with the Spartan was unique. So long as they shared the same armor they would share the same fate. If he died then she died. Relationships don’t get any more interdependent than that, something that struck Cortana as both wonderful and frightening.

His boots made a hollow sound as he approached the gigantic blast doors and hit the switch. They parted to reveal a battle in progress between a group of Sentinels and Covenant ground troops. Red lasers split the air into jagged shapes as robots burned a Jackal down. The contest was far from one-sided, however, as one of the machines exploded and showered the Covenant with bits of hot metal.

The room was a long rectangular affair with a strangely corrugated floor.

Standing at one end of the space, and well out of harm’s way, the Spartan was content to watch and let the two groups whittle each other down.

However, when the last robot crashed, leaving two Elites still on their feet, the Master Chief knew he’d have to take them on.

The Covenant spotted the human, knew he’d have to come to them, and stood waiting. The Chief took advantage of what little bit of cover there was and made his way down the length of the room. With only half a clip of ammo left in his assault rifle, he had little choice but to tackle them with the shotgun—far from ideal at this range.

He fired a couple of rounds just to get their attention, waited for the Elites to charge, and lobbed a plasma grenade into the gap between them. The explosion killed one soldier and wounded the other. A single blast from the shotgun was sufficient to finish the job. Striding though the carnage, he exchanged the assault weapon for a plasma rifle.

From there it was a short journey through an empty room and out onto the top level of the pyramid. It was dark, and a fresh layer of snow had fallen since the time when the noncom had battled his way up to the Control Room from the valley below.

There were guards, but all of them had their backs to the hatch, and didn’t bother to turn until the doors were halfway open. That was when they saw the human, did a series of double takes, and started to respond. But the Chief was ready and used the energy weapon to hose them down. The Elites jerked and fell, quickly followed by several Jackals and Grunts.

Then, just as suddenly as the violence had started, it was over. Snow swirled around the sole figure who remained standing, began the long, painstaking job of covering each body with a shroud of white, and fostered an illusion of peace.

Cortana took advantage of the momentary pause to update the Spartan regarding her plan. “We need to buy some time in case the Monitor or his Sentinels find a way to activate Halo’s final weapon without the Index.

“The machines in these canyons are Halo’s primary firing mechanisms.

They consist of three phase pulse generators that amplify Halo’s signal and allow it to fire deep into space. If we damage or destroy the generators, the Monitor will need to repair them before Halo can be used. That should buy us some time. I’m marking the location of the nearest pulse generator with a nav point. We need to move and neutralize the device.”

“Roger that,” the Chief said, as he made his way down the first ramp to the platform below. Once again the element of surprise worked in his favor. He killed two Elites, caught a couple of Jackals as they tried to run, and nailed a Grunt as it appeared from below.

The wind whistled around the side of the pyramid. The Spartan left a trail of large bootprints as he made his way down to the point where the ramp met the next level walkway, crossed to the other side of the structure, and ran into a pair of Elites as they hit the top of the up ramp and rounded the corner.

There wasn’t enough time to do anything but fire, and keep on firing, in an attempt to overwhelm the Covenant armor. It wouldn’t have worked had the aliens been farther away, but the fact that the plasma pulses were pounding them in close made all the difference. The first Elite made a horrible gurgling sound as he fell and the second got a shot off but lost half of his face. He brought his hands up to the hole, made a gruesome discovery, and was just about to scream when an energy bolt took his life.

Then, as the Spartan prepared to descend into the valley below, Cortana said, “Wait, we should commandeer one of those Banshees. We’ll need it to reach the pulse generator in time.” Like many of the AI’s suggestions, this was easier said than done, but the Chief was in favor of speed, and filed the possibility away.

Now, as he came down off the pyramid, he saw lots of Covenant, but no Flood, and felt a strange sense of relief. The Covenant were tough, but he understood them, and that lessened his apprehension.

The alien plasma rifle lacked the precision offered by an M6D pistol or a sniper’s rifle, but the Chief did the best he could to pick off some of the Covenant below. Still, he had only nailed three of the aliens when his efforts attracted the attention of a Wraith tank, along with more troops. There was nothing he could do except retreat back uphill.

The Wraith, which continued to hurl plasma bombs up-slope, actually helped by preventing other Covenant forces from charging after him. That advantage wouldn’t last long, though, which meant that he had to find some additional fire power, and find it fast.

Even though there was no sign of the Flood at the moment, some of their half-frozen bodies lay scattered about, suggesting that there had been a significant battle within the last couple of hours. He knew the Flood carried weapons acquired from dead victims, so the Chief ran from corpse to corpse, looking for what he required. For a while it seemed hopeless as he uncovered a series of M6Ds, energy pistols, combat knives, and other gear— anything and everything except what he needed most.

Then, just when he had nearly given up hope, he saw a few inches of olive drab tubing protruding from under a dead combat form. He rolled the ex- Elite over, and felt a rising sense of excitement. Was the launcher loaded? If so, he was in luck.

A quick check revealed that the weapon was loaded, and as if to prove that luck comes in threes, the Spartan found two reloads only a few meters away.

Armed with the launcher, he was ready to go to work. The Wraith represented the most significant threat, so he decided to deal with that first.

It took time to make his way back across the face of the pyramid to a point where he could get a clear shot, but he did. The monster was dangerously close as he put a pair of rockets into the mortar tank, and watched it explode.

He ejected the spent rocket tubes, slammed a reload home, and shifted his aim. Two more rockets lanced ahead, and detonated in clusters of Covenant soldiers. He fell back and slung the rocket launcher; he had a limited supply of rockets, and once they were gone, he had no choice but to go down onto the valley floor and finish the job the hard way.

He crept up on the pair of Elites who stood guard near a Banshee. They went down from deadly, spine-cracking blows and he stepped past their fallen corpses. He examined the Banshee’s controls while Cortana pulled up files the tech boys in Intel had prepared based on examinations of captured craft.

He boarded the single-seat aircraft, and activated its power plant. He wondered why the aliens hadn’t used the ship against him, was thankful that they hadn’t, and eyed the instrument panel. The Master Chief had never flown one of the attack ships before, but was qualified to fly most of the UNSC’s atmospheric and spacegoing ships so, between his own experience and the tech files Cortana provided, he found the controls relatively easy to understand. The takeoff was a bit wobbly, but it wasn’t long before the flight began to smooth out, and the Banshee started to climb.

It was dark, and snow continued to fall, which meant that visibility was poor. He kept a close eye on both the nav point Cortana had projected onto his HUD and the instrument panel. The design was different, but an alien turn and bank indicator still looked like what it was, and helped the human maintain his orientation.

The attack ship made good speed, and the valleys were quite close together, so it wasn’t long before the Spartan spotted the well-lit platform which jutted out from the face of the cliff, as well as the enemy fire which lashed up to greet him. The word was out, it seemed—and the Covenant didn’t want any visitors.

Rather than put down under fire, he decided to carry out a couple of strafing runs first. He swooped low and used the Banshee’s plasma and fuel rod cannons to sweep the platform clear of sentries before decelerating for what he hoped would be an unopposed landing.

The Banshee crunched into the platform, bounced once, then ground to a halt. The Chief dismounted, passed through a hatch, and entered the tunnel beyond.

“We need to interrupt the pulse generator’s energy stream,” Cortana informed him. “I have adjusted your shield system so that it will deliver an EMP burst and disrupt the generator . . . but you’ll have to walk into the beam to trigger it.”

The Master Chief paused just shy of the next hatch. “I’ll have to do what ?”

“You’ll have to walk into the beam to trigger it,” the AI repeated matter-of- factly. “The EMP blast should neutralize the generator.”

“Should?” the Chief demanded. “Whose side are you on?”

“Yours,” Cortana replied firmly. “We’re in this together—remember?”

“Yeah, I remember,” the Spartan growled. “But you’re not the one with the bruises.”

The AI chose to remain silent as the Chief passed through a hatch, paused to see if anyone would attempt to cancel his ticket, and followed the nav indicator to the chamber located at the center of the room.

Once he was there the pulse generator was impossible to miss. It was so intensely white that his visor automatically darkened in order to protect his eyes. Not only that, but the Chief could feel the air crackle around him as he approached the delta-shaped guide structures, and prepared to step in between them. “I have to walk into that thing?” the Chief inquired doubtfully. “Isn’t there some easier way to commit suicide?”

“You’ll be fine,” Cortana replied soothingly. “I’m almost sure of it.”

The Spartan took note of the “almost,” clenched his teeth, and pushed himself into the blindingly intense light. The response was nearly instantaneous. There was something akin to an explosion, the light started to pulsate, and the floor shook in response. The Chief hurried to disengage, felt a bit of suction, but managed to pull free. As he did so he noticed that his shields had been drained. His skin felt sunburned.

“The pulse generator’s central core is off-line,” Cortana said. “Well done.”

Another squadron of Sentinels arrived. They swooped into the cramped pulse-generator chamber like vultures, fanned out, and seared the area with ruby-red energy beams. Not only did the Monitor take exception to the damage—he was after the Index too.

But the Chief knew how to deal with the mechanical killers, and proceeded to dodge their lasers as he destroyed one after another. Finally, the air thick with the stench of ozone, he was free to withdraw. He went back through the same tunnel to the platform where the Banshee waited.

“The second pulse generator is located in an adjacent canyon,” Cortana announced easily. “Move out and I’ll mark the nav point when we get closer.”

The Master Chief sent the Banshee into a wide bank, and toward the next objective.

Minus the refrigeration required to preserve them, the bodies laid out on the metal tables had already started to decay, and the stench forced Silva to breathe through his mouth as he entered the makeshift morgue and waited for McKay to begin her presentation.

Six heavily armed Helljumpers were lined up along one wall ready to respond if one or more of the Flood suddenly came back to life. It seemed unlikely given the level of damage each corpse had sustained, but the creatures had proven themselves to be extremely resilient, and had an alarming tendency to reanimate.

McKay, who was still trying to deal with the fact that more than fifteen Marines under her command had lost their lives in a single battle, looked pale. Silva understood, even sympathized, but couldn’t allow that to show.

There was simply no time for grief, self-doubt, or guilt. The Company Commander would have to do what he did, which was to suck it up and keep on going. He nodded coolly.

“Lieutenant?”

McKay swallowed in an attempt to counter the nausea she felt. “Sir, yes sir.

Obviously there’s still a great deal that we don’t know, but based on our observations during the fight, and information obtained from Covenant POWs, here’s the best intelligence we have. It seems that the Covenant came here searching for ‘holy relics’—we think that means useful technology— and ran into a life form they refer to as ‘the Flood.’ ” She gestured at the fallen creatures on the slab. “Those are Flood.”

“Charming,” Silva muttered.

“As best we can figure out,” McKay said, “the Flood is a parasitic life form which attacks sentient beings, erases their minds, and takes control of their bodies. Wellsley believes that Halo was constructed to house them, to keep them under control, but we have no direct evidence to support that. Perhaps Cortana or the Chief can confirm our findings when we’re able to make contact with them again.

“The Flood manifests in various forms starting with these things,” McKay said, using her combat knife to prod a flaccid infection form. “As you can see, it has tentacles in place of legs, plus a couple of extremely sharp penetrators, which they use to invade the victim’s central nervous system and take control of it. Eventually they work their way inside the host body and take up residence there.”

Silva tried to imagine what that might feel like and felt a shiver run down his spine. Outwardly he was unchanged. “Please continue.”

McKay said, “Yes, sir,” and moved to the next table. “This is what the Covenant call a ‘combat form.’ As you can see from what remains of its face, this one was human. We think she was a Navy weapons tech, based on the tattoos still visible on her skin. If you peek through the hole in her chest you can see the remains of the infection form that deflated itself enough to fit in around her heart and lungs.”

Silva didn’t want to look, but felt he had to, and moved close enough to see the wrinkled scalp, to which a few isolated clumps of filthy hair still clung.

His eyes catalogued a parade of horrors: the sickly looking skin; the alarmingly blue eyes which still bulged, as if in response to some unimaginable pain; the twisted, toothless mouth; the slightly puckered 7.62mm bullet hole through the right cheekbone; the lumpy, penetrator-filled neck; the bony chest, now split down the middle so that the woman’s flat breasts hung down to either side; the grossly distorted torso, punctured by three overlapping bullet wounds; the thin, sinewy arms; and the strangely graceful fingers, one of which still bore a silver ring.

The Major didn’t say anything, but his face must have telegraphed what he felt, because McKay nodded. “It’s pretty awful, isn’t it, sir? I’ve seen death before, sir—” she swallowed and shook her head, “—but nothing like this.

“For what it’s worth Covenant victims don’t look any better. This individual was armed with a pistol, her own probably, but the Flood seem to pick up and use any weapon they can lay their hands on. Not only that, but they pack a very nasty punch, which can be lethal.

“Most combat forms appear to be derived from humans and Elites,” McKay continued, as she moved to the last table. “We suspect that Grunts and Jackals are deemed too small for first-class combat material, and are therefore used as a sort of nucleus around which carrier forms can grow. It’s hard to tell by looking at the puddle of crap on the table in front of you, but at one time this thing contained four of the infection forms you saw earlier, and when it popped the resulting explosion had enough force to knock Sergeant Lister on his can.”

That, or the mental picture that it conveyed, was sufficient to elicit nervous grins from the Helljumpers who lined the back wall. Apparently they liked the idea of something that could put Lister on his ass.

Silva frowned. “Does Wellsley have scans of this stuff?”

“Yes, sir.”

“Excellent. Nice job. Have the bodies burned, send these troops up for some fresh air, and report to my office in an hour.”

McKay nodded. “Yes, sir.”

Zuka ’Zamamee lay belly down on the hard-packed dirt and used his monocular to scan the Pillar of Autumn . It wasn’t heavily guarded; the Covenant was stretched too thin for that, but the Council had reinforced the security force subsequent to the human raid, and evidence of that was visible in the Banshees, Ghosts, and Wraiths that patrolled the area around the downed ship. Yayap, who lay next to the Elite, had no such device and was forced to rely on his own vision.

“This plan is insane,” ’Zamamee said out of the side of his mouth. “I should have killed you a long time ago.”

“Yes, Excellency,” the Grunt agreed patiently, knowing that the talk was just that. The truth was that the officer was afraid to return to the Truth and Reconciliation , and now had very little choice but to accept Yayap’s plan, especially in light of the fact that he had been unable to come up with one of his own.

“Give it to me one more time,” the Elite demanded, “so I’ll know that you won’t make any mistakes.”

Yayap eyed the readout on his wrist. He had two, maybe two and a half units of methane left, before his tanks were empty and he would suffocate, a problem which didn’t seem to trouble the Elite at all. It was tempting to pull his pistol, shoot ’Zamamee in the head, and implement the strategy on his own. But there were advantages to being in company with the warrior—plus a giddy sense of power that went with having threatened the warrior and survived. With that in mind Yayap managed to suppress both his panic and a rising sense of resentment.

“Of course, Excellency. As you know, simple plans are often best, which is why there is a good chance this one will work. On the possibility that the Council of Masters is actively looking for Zuka ’Zamamee, you will choose one of the commandos who died on the human encampment, and assume that individual’s identity.

“Then, with me at your side, we will report to the officer in charge of guarding the alien ship, explain that we were taken prisoner in the aftermath of the raid, but were subsequently able to escape.”

“But what then?” the Elite inquired warily. “What if he submits my DNA for a match?”

“Why would he do that?” the Grunt countered patiently. “He’s shorthanded, and here, as if presented by the great ones themselves, is a commando Elite.

Would you run the risk of having such a find reassigned? No, I think not.

Under circumstances such as these you would seize the opportunity to add such a highly capable warrior to your command, and give thanks for the blessing.”

It sounded good, especially the “highly capable warrior” part, so ’Zamamee agreed. “Fine. What about later?”

“Later, if there is a later,” Yayap said wearily, “we will have to come up with another plan. In the meantime this initiative will assure us of food, water, and methane.”

“All right,” ’Zamamee said, “let’s jump on the Banshee and make our appearance.”

“Are you sure that’s the best idea?” the Grunt inquired tactfully. “If we arrive on a Banshee, the commanding officer might wonder why we were so slow to check in.”

The Elite eyed what looked like a long, hard walk, sighed, and acquiesced.

“Agreed.” A hint of his former arrogance resurfaced. “But you will carry my gear.”

“Of course,” Yayap said, scrambling to his feet. “Was there ever any doubt?”

The inmate had attempted suicide twice, which was why the interior of his cell was bare, and under round-the-clock surveillance. The creature that had once been Private Wallace A. Jenkins sat on the floor with both wrists chained to an eyebolt located just over his head.

The Flood mind, which the human continued to think of as “the other,” had been quiet for a while, but was present nonetheless, and glowered in what amounted to a cognitive corner, angry but weak. Hinges squealed as the metal door swung open. Jenkins turned to look, and saw a male noncom enter the room followed by a female officer.

The private felt an almost overwhelming sense of shame—and did what he could to turn away. Earlier, before the guards secured his wrists to the wall, Jenkins had used pantomime to request a mirror. A well-meaning Corporal brought one in, held it up in front of the soldier’s devastated face, and was frightened when he tried to scream. The initial suicide attempt followed thirty minutes later.

McKay took a look at the prisoner’s dry, parched lips and guessed that he might be thirsty. She called for some water, accepted a canteen, and started across the cell. “With respect, ma’am, I don’t think you should do that,” the Sergeant said cautiously. “These suckers are incredibly violent.”

“Jenkins is a Private in the UNSC Marine Corps,” McKay replied sternly, “and will be referred to as such. And your concern has been noted.”

Then, like a teacher dealing with a recalcitrant child, she held the canteen out where Jenkins could see it. “Look!” she said, sloshing the water back and forth. “Behave yourself and I’ll give you a drink.”

Jenkins tried to warn her, tried to say “No,” but heard himself gabble instead. Thus encouraged, McKay unscrewed the canteen’s lid, took three steps forward, and was just about to lean over when the combat form attacked. Jenkins felt his left arm break as the chain brought it up short—and fought to counter the other’s attempt to grab the officer in a scissor lock.

McKay stepped back just in time to evade the flailing legs.

There was a clacking sound as the guard pumped a shell into the shotgun’s receiver and prepared to fire. McKay shouted, “No!” and held up her hand.

The noncom obeyed but kept his weapon aimed at the combat form’s head.

“Okay,” McKay said, looking into the creature’s eyes, “have it your way.

But, like it or not, we’re going to have a talk.”

Silva had entered the cell by then and stood behind the Lieutenant. The Sergeant saw the Major nod, and backed into a corner with his weapon still held at the ready.

“My name is Silva,” the Major began, “and you already know Lieutenant McKay here. First, let me say that both of us are extremely sorry about what happened to you, we understand how you feel, and will make sure that you receive the best medical care that the UNSC has to offer. But first we have to fight our way off this ring. I think I know how we can do that—but it will take some time. We need to hold this butte until we’re ready to make our move. That’s where you come in. You know where we are now—and you know how the Flood move around. If you had my job, if you had to defend this base against the Flood, where would you focus your efforts?”

The other used his right hand to grab his left, jerked hard, and exposed a shard of broken bone. Then, as if hoping to use that as a knife, the combat form lunged forward. The chains brought the creature up short. Jenkins felt indescribable pain, began to lose consciousness, but fought his way back.

Silva looked at McKay and shrugged. “Well, it was worth a try, but it looks like he’s too far gone.”

Jenkins half expected the other to lunge forward again, but having shared in the human’s pain, the alien consciousness chose that moment to retreat. The human surged into the gap, made hooting sounds, and used his good hand to point at Silva’s right boot.

The officer looked down at his boot, frowned, and was about to say something when McKay touched his arm. “He isn’t pointing at your boot, sir, he’s pointing down . At the area under the butte.”

Silva felt something cold trickle into his veins. “Is that right, son? The Flood could be directly below us?”

Jenkins nodded emphatically, rolled his eyes, and made inarticulate gagging sounds.

The Major nodded and came to his feet. “Thank you, Private. We’ll check the basement and be back to speak with you some more.”

Jenkins didn’t want to talk, he wanted to die , but nobody cared. The guards left, the door clanged shut, and the Marine was left with nothing but a broken arm and the alien inside his head. Somehow, without actually dying, he had been sentenced to hell.

As if to confirm that conclusion the other surged to the fore, yanked at the chains, and beat its feet on the floor. Food had been present, food had left, and it remained hungry.

The Master Chief spotted the next way point, put the hijacked Banshee down on a platform, and entered the complex via an unguarded hatch. He heard the battle before he actually saw it, made his way through the intervening tunnel, and peered through the next door. As had occurred before, the Covenant was busy taking it to the Flood and vice versa, so he gave both groups some time to whittle each other down, left the security of the tunnel, and proceeded to tidy up.

Then, eager to replenish his supplies, the Spartan made his ghoulish rounds, and soon was able to equip himself with an assault weapon, a shotgun, and some plasma grenades. Even though he didn’t like to think about where it came from, it felt good to dump the Covenant ordnance he’d been saddled with, and lay his hands on some true-blue UNSC issue for a change.

Pulse generator one had been dealt with, and he was eager to disable number two, then move on to his final objective. He stepped into the beam, saw the flash of light, felt the floor shake, and was in the process of pulling away when the Flood attacked from every direction.

There was no time to think and no time to fight. The only thing he could do was run. He turned and sprinted for the corridor he’d used to enter the chamber and took two powerful blows from a combat form. He bulled his way between two carrier forms and leaped out of the way as they detonated like grenades. New infection forms spewed from their deflating corpses.

There was barely enough time to turn, hose the closest forms with 7.62mm, and toss a grenade at the group beyond. It went off with a loud wham! , broke glass, and put three of the monstrosities down.

He was out of ammo by then, knew he lacked the time necessary to reload, and made the switch to the shotgun instead. The gun blew huge holes through the oncoming mob. He charged through one of them, and ran like hell.

Then, with some pad to work with, the human turned to gun down the pursuers. The entire battle consumed no more than two minutes but it left the Chief shaken. Could Cortana detect the slight tremor in his hands as he reloaded both weapons? Hell, she had unrestricted access to all of his vital signs, so she knew more about what was going on with his body than he did.

Still, if the AI was conscious of the way he felt, there was no sign of it in her words. “Pulse generator deactivated—good work.”

The Chief nodded wordlessly and made his way back through the tunnel to the point where the Banshee waited. “The Pillar of Autumn is located twelve hundred kilometers up-spin,” Cortana continued. “Energy readings show her fusion reactors are still powered up! The systems on the Pillar of Autumn have fail-safes even I can’t override without authorization from the Captain.

We’ll have to find him, or his neural implants, to start the fusion core detonation.

“One target remaining. Let’s take care of the final pulse generator.”

A nav indicator appeared on the noncom’s HUD as he lifted off, took fire from a neighboring installation, and put the attack ship into a steep dive. The ground came up fast, he pulled out, and guided the alien assault craft through a pass and into the canyon beyond. The nav indicator pointed toward the light that spilled out of a tunnel. The Banshee began to take ground fire, and the Spartan knew his piloting skills were about to be severely tested.

A rocket flashed by as he pushed the Banshee down onto the deck, fired the aircraft’s weapons, and cut power. Flying into the tunnel was bad enough— but flying into it at high speed verged on suicidal.

Once inside the passageway the challenge was to stay off the walls and make the tight right- and left-hand turns without killing himself. A few seconds later the Spartan saw double blast doors and flared in for a jarring landing.

He hopped down, made his way over to the control panel, hit the switch, and heard a rumbling sound as the doors started to part. Then there was a bang!

as something exploded and the enormous panels came to a sudden stop. The resulting gap was too small for the Banshee, but sufficient for two carrier forms to scuttle through. The beasts scrambled toward him on short, stubby legs. The humpbacked bladders that formed their upper torsos pulsed and wriggled as the infection forms within struggled for release.

The Chief blew both monsters away with twin shotgun blasts, and mopped up the rest of the infection forms with another shot. He paused and reloaded; there were bound to be more of the creatures on the far side of the doors.

Resigned to a fight, he stepped through the crack and paused. There was no sound beyond the gentle roar of machinery, the drip, drip, drip of water off to his right, and the rasp of his own breathing. The threat indicator was clear, and there were no enemies in sight, but that didn’t mean much. Not where the Flood were concerned. They had a habit of coming out of nowhere.

The cave, if that was the proper word for the huge cavernlike space, featured plenty of places to hide. Enormous pipes emerged from the walls and dived downward, mysterious installations stood like islands on the platform around him, and there was no way to know what might lurk in the dark corners.

Lights, mounted high above, provided what little illumination there was.

The human stood on a broad platform that ran the full length of the open area. A deep chasm separated his platform from what appeared to be an identical structure on the other side of the canyon. One of two bridges that had once spanned the gorge was down, leaving only one over which he could pass—a made-to-order choke point for anyone who wanted to establish an ambush.

There wasn’t a hell of a lot of choice, so he marched down to the point where the remaining span was anchored, and started across. He hadn’t gone more than thirty paces before fifty or sixty infection forms emerged from hiding and danced out to block the way.

The Spartan held his position, waited for the Flood forms to come a little closer, and tossed a fragmentation grenade into the center of the group.

The cavern ate some of the sound, but the explosive device still managed to produce a bang , and the resulting shrapnel laid waste to all but a handful of the creatures.

There were two survivors, though, both optimists, who continued to bounce forward in spite of the way in which the rest of the group had been annihilated. A single shotgun blast was sufficient to kill both of them.

He slipped some additional shells into the gun’s magazine tube, took a deep breath, and moved forward again. He made it about halfway to the other side before a mixed force of combat forms, carrier forms, and infection forms started to gather at the far end of the span. Another grenade inflicted casualties, but they charged him after that, and the Master Chief was forced to retreat, firing the assault weapon as he did so.

It was nip and tuck for a few seconds as combat forms launched themselves fifteen meters through the air, carriers charged straight in, and the omnipresent infection forms swarmed through the gaps. Retreating, the Spartan had already reloaded three times before his back hit the wall, and the last combat form collapsed at his feet, started to rise, and took a blast in the head.

Once again it was time to reload both weapons, step out onto the gore- splattered bridge deck, and attempt another crossing. This one was successful, with only light opposition on the other side, and an opportunity to replenish his ammo.

The next set of blast doors opened flawlessly, allowing the Spartan to enter a relatively short section of tunnel that led back to the surface. Determined to use stealth if at all possible, he slipped out of the passageway, scrambled up over the snow embankment to his right, and ran into a group of four Flood.

A grenade took care of two—and the assault weapon finished the rest.

A Banshee swooped in, burned a long line of dashes into the snow, and continued up the valley. The Chief was surprised to get off so lightly, but given the darkness and all of the confusion, it was possible that the pilot had mistaken him for a combat form. A worthy target, to be sure, but not something to turn around for. Particularly not when the valley was full of combat forms.

He was careful to hug the face of the cliff and stay within the cover provided by the boulders and trees that lined the edge of the valley. The incessant thud of automatic weapons and the whine of plasma weapons testified to the intensity of a conflict raging off to his left.

Then, just as he was starting to believe that he could slide by without firing a shot, he came up over a slight rise to see that the Covenant and Flood were engaged in hand-to-hand combat within the depression below. A grenade followed with bursts of fire from the MA5B decimated both groups.

Snow crunched as the human made his way down through the bloodstained snow, past the spot where a trio of greedy infection forms squabbled over a wounded Elite, and up another rise to a stand of trees where a combat form and a carrier tried to jump him. Both of the Flood staggered as bursts of 7.62mm slugs cut them down, and they flopped onto the snow.

Having broken through the perimeter of the battle, the Master Chief was able to follow the nav indicator into a second valley where he came upon a group of dead Marines, loaded up on ammo, and tried to decide whether to stay with the scatter gun or trade it in for a sniper’s rifle or a rocket launcher. It would have been nice to have all three, but that many weapons would be unwieldy, not to mention damned heavy. In the end he went with the rifle and shotgun and hoped it was the right decision.

The Spartan checked the Marines for dog tags, discovered that they had already been taken by someone else, and took the time required to drag the bodies into a nearby cave in the hope that the infection forms wouldn’t find them. That seemed like a good place to stash the extra weapons—so that’s what he did.

Then, having followed the second valley to the point where it opened onto a third valley, he came across a now-familiar scene. The Covenant were battling the Flood with everything they had, including Shades, a brace of Ghosts, and two extremely active Wraiths, but the Flood had plenty of bodies to throw back at them and didn’t hesitate to do so.

What the Chief wanted was the Banshee that was parked at the head of the valley, but in order to get at the aircraft it would be necessary to cut both groups down to size. He stayed right, slipped along the cliff face, made use of a thin screen of trees and boulders to hide his movements from those out toward the center of the valley. Finally, having passed behind a house-sized rock and found a vantage point that allowed him to look out on the area where the vast majority of the Covenant were congregated, the Spartan unlimbered the S2 AM, selected the 10X setting for the scope, and began his bloody work.

In this particular situation he selected the softest targets first, starting with the Grunts on the Shades, followed by the outlying Jackals, all in hope that he could inflict a lot of casualties before the Elites took notice and sent the tank to get him.

The problem was that the little world inside the scope was all-consuming—a fact that caused him to let down his guard. The first hint he had that a Flood form had come up behind him was when it whacked the Spartan in the head.

The blow would have killed anyone else, but the armor saved him, and the Chief rolled in the direction of the blow. The long-barreled S2 wasn’t well suited for close-in combat but that’s what he had in his hands. There was no time to aim as the Flood form charged, only time to fire, and that’s what he did.

The slug caught the ex-Elite in the chest. The combat form didn’t even flinch as the bullet passed through its spongy center of mass. A tiny spurt of gray-green ichor trailed from the entry wound, as the creature swung a vicious blow at the Master Chief.

He ducked the attack and dropped the rifle. He dived, tucked into a roll and came up with his sidearm in his hand. He emptied the clip into the beast.

One round blew its left arm off, and the final round made a foot-wide exit wound in the Flood’s back.

He kicked in the creature’s chest, crushing the infection form within. He collected the S2, and frowned. He studied the fallen Flood for a moment, and saw that the creature’s insides were rapidly liquefying. The velocity of the S2’s projectile had passed through the nonvital mass of the creature’s chest and just kept going.

Another nasty surprise, courtesy of the Flood.

After a quick look around to make sure that there weren’t any more surprises lurking in the vicinity, with his heart still beating like a trip-hammer, the Chief went back to his grisly work. Three more Covenant warriors fell before a barrage of fireballs arced high into the air to land all around his position. One came so close that just the bleed off it was enough to push his shielding into the red and trigger the alarm.

He pulled back, switched to the assault weapon long enough to ice a couple of overly ambitious Grunts, and switched back to the S2 as he rounded the opposite side of the big boulder. He selected a spot where he could go to work on both the Covenant and the Flood, and settled in.

He wanted to nail the Elites now and, thanks to the powerful 14.5mm armor- piercing rounds, he could drop most of them with a single shot. Combat forms were a different story, so he switched to the pistol. It was less accurate, but did the job. It wasn’t long before more than a dozen bodies were laid out in the snow. But then the word was out. Soon the mortar tank moved into position to bombard his new position, and it was necessary to pull back.

The Wraith was a problem, a serious problem, which meant there was only one thing the Spartan could do: hike back to the weapons cache and trade the rifle for the launcher. It was a major pain in the ass, but he didn’t have much choice, so he pulled out.

It took a full half hour to make the round trip between the valley and the weapons cache, so he expected things to have calmed down a bit by the time he returned. That wasn’t the case, however, which suggested that the Flood had thrown even more forms into the battle.

The Chief followed his own footprints back to the hiding place next to the big boulder, put the launcher on his shoulder, and hit the zoom. The Wraith, which was busy hurling bombs down valley, seemed to leap forward. As if somehow aware of his presence, the tank spun on its axis, and launched a bomb toward the rock.

The Spartan forced himself to ignore the artificial comet, locked onto the target, and triggered the rocket. There was an impact and a loud crump!

followed by smoke—but the Wraith continued to fire nonetheless.

Now, with fireballs exploding all around him, the Master Chief had to take a deep breath, hold the tank at the center of his sight, and pull the trigger again. The tube jerked, the second missile ran straight and true, and hit with a loud craack! The Wraith opened like a red flower, burped pitch-black smoke, and nosed into a snowbank.

“Nice shot,” Cortana said admiringly, “but watch the Ghost.”

It was good advice, because although the attack vehicle had held back up to that point, it came skittering into sight, opened up with its plasma weapons, and threatened to accomplish what the rest of the Covenant soldiers hadn’t.

But the Chief had reloaded by then. The rocket tube was the right weapon for the job, and a single missile was sufficient to send the attack vehicle flipping end-for-end to finally wind up with its belly in the air and flames licking at the engine compartment.

With that problem out of the way the Chief came to his feet, slapped a fresh load into the launcher, and made a beeline for the Banshee. He was halfway across, with nowhere to hide, when a pair of Hunters emerged from a jumble of boulders.

Now, grateful that he still had some rockets, he had no choice but to stop, drop to one knee, and take them on. The first shot was dead on, hit the alien in the chest, and blew the bastard apart. Another rocket flew over the second Hunter’s right shoulder and cut a tree in half. The big alien started to lumber across open ground, picking up speed and charging its arm-mounted cannon.

It was a waste of ammo to pepper the front end of a Hunter with 7.62mm rounds, and slow though he was, the alien could still bring him down with a blast from his arm-mounted fuel rod cannon.

So he put his sight onto a target so big he didn’t need to zoom, and let fly.

The Hunter saw the missile coming, tried to deflect it with his shield, and failed. Seconds later pieces of warm meat showered the area, melted holes in the snow, and continued to steam.

The Chief ran past without a second look, jumped onto the Banshee, and strafed the rest of the Covenant forces on his way down the valley. Judging from the way the nav indicator was oriented, the Spartan needed altitude, a lot of it, so he put the alien attack ship into a steep climb.

Finally, when the red delta flipped over, and started to point down, he knew he was high enough. He did a nose-over and caught his first glimpse of the way point below. The surrounding area was dark, and snow continued to fall, but the platform was nicely lit. He lowered the Banshee onto the pad and had just bailed out of the pilot’s seat when the Sentinels attacked. “This is the last one,” Cortana said. “The Monitor will do anything to stop us.”

The Chief blew three of the pesky machines out of the air, backed through the hatch, and let the door close on the rest.

“We’re close,” the AI commented. “The generator is up ahead.”

The Chief nodded, stepped out into a room, and felt a laser burn across the front of his armor. It seemed that the Monitor had posted Sentinels inside the complex, as well. Not only that, but these machines had benefit of intermittent force fields, which were resistant to automatic weapons fire.

Still, he had a couple of 102mm surprises in store for the electromechanical enforcers, which he fired into the center of the hovering pack. Three Sentinels were blown out of the air. A fourth did loops as it tried to rid itself of a plasma grenade, failed, and took another machine with it. The fifth and sixth succumbed to a hail of bullets as their shields recharged, while the seventh slammed into a wall, crashed to the floor, and was busy trying to lift off again when the Chief stomped it to death.

The way was clear at that point and the Spartan was quick to take advantage of it. A few quick strides were sufficient to carry him into the central chamber where he was free to approach the final pulse generator.

“Final target neutralized,” Cortana said as the noncom stepped back a few moments later. “Let’s get out of here.”

“Let’s find a ride and get to the Captain,” the Chief agreed, as he prepared to leave.

“No, that’ll take too long.”

“Do you have a better idea?”

“There’s a teleportation grid that runs around Halo. That’s how the Monitor moves about so quickly,” the AI explained. “I learned how to tap into the grid when I was in the Control Center.”

“So,” the Chief asked, somewhat annoyed, “why didn’t you just teleport us to the pulse generators?”

“I can’t. Unfortunately, each jump requires a rather consequential expenditure of energy, and I don’t have access to Halo’s power systems to reroute the energy we need.” She paused, then reluctantly continued. “There may be another way, however.”

The Spartan frowned and shook his head. “Something tells me I’m not going to like this.”

“I’m pretty sure I can pull the energy we need from your suit without permanently damaging your shield system or the armor’s power cells,” Cortana continued. “Needless to say, I think we should only try this once.”

“Agreed. Tap into the Covenant network and see if you can find him. If we’ve only got one shot at this, we should make it a good one.”

There was a pause as Cortana worked her magic with the intrusion and scan software. A moment later, she exclaimed, “I’ve got a good lock on Captain Keyes’ CNI transponder signal. He’s alive! And the implants are intact!

There’s some interference from the cruiser’s damaged reactor. I’ll bring us in as close as I can.”

“Do it,” the Master Chief growled. “Let’s get this over with.”

No sooner had the Spartan spoken than bands of golden light started to ripple down over his armor, the now-familiar feeling of nausea returned, and the Master Chief seemed to vanish through the floor. Once he was gone only a few motes of amber light remained to mark his passing. Then, after a few seconds, they too disappeared.
