Disclaimer: I Do Not Own Naruto Or Halo

(DarkShadowRaven: Thanks for the review and as for robots I think it's because in a data-chip they would be easier to move in combat instead of the Spartans having to protect and actual body. But for when they're on the ships it would cool for Cortana to have a robot body to plug her chip into instead of just the holo-tables. With how advanced their technology is it should be easy to build her one.

(General Zod: For the A.I, he doesn't have one because UNSC protocol is that an A.I cannot fall into enemy hands. Like when Chief took Cortana when the Pillar of Autumnm was going down. I wasn't going to get into it but your question did give me and idea so thank you very much for asking it.

(Cryo threshold: Glad you like the story, and thank you for the correction.

"All clear Sarge." Corporal McMillan whispered aiming a shaking MA5C down the empty hallway he had been tasked to check while Sergeant James checked the rooms.

"Rooms clear!"

Lifting an elbow he wiped the sweat from his temple letting out a weak laugh when the Sergeant yelled back. At least the guys here survived whatever the hell had happened.

"You good, Marine?"

"Yea, Sarge just peachy. I'm used to seeing all my friends die." McMillan thought scowling at the older man's nonchalant attitude. "Not everyone was in the Great War Sarge, as a matter of fact, most of the people stationed here weren't."

"I know that McMillan but right now we don't have time to worry about the dead when we still have to protect the living," James said as he grabbed the Corporals shoulder squeezing softly. "The Doctors and are fellow Marines stationed here are counting on us. We can't let them down."

Nodding McMillan smiled giving the Sarge a half-hearted salute. "You got it Sa-"

Flinching as a loud bang echoed from the hallway McMillan didn't wait for the Sergeants orders immediately opening fire down the hallway.

"Dammit, friendly fire! Friendly Fire!"

"McMillan, stop shooting!"

Startled McMillan lifted his finger off the trigger lowering his rifle and his head as a black armored figure ducked into cover at the end of the hallway. "Sir...I."

"Keep your weapon down Corporal." James hissed pushing the Corporal away from the hallway. Dammit, the kid was a kid but he was also a soldier. And almost killing a friendly because of his nerves wasn't something he needed from the men under his command.
"Identify yourself!" He called out keeping behind cover just in case.

"Captain Naruto Uzumaki, ODST!"

After yelling out his name Naruto took off his helmet as he stepped out of cover slowly, his muscles tensed ready to dive back at a moment's notice. If it wasn't for his reflexes from Project Rebirth being honed over the years he spent in open combat with Covenant soldiers, the two slugs in his shoulder plate could have easily been embedded in his head.

"Sergeant James, your guy under control?"

"Yes sir, sorry sir."

"I'm not dead so no harm done," Naruto had seen enough jittery Marines firing at ghosts on the battlefield to recognize a rookie.

Walking down the hallway he came to a stop helmet still in hand waving it slightly. "I heard your plan over the radio but my comms are fried I couldn't let you know I was coming. Find any survivors yet?"

"No, just a few bodies of the people that didn't make it inside before the shockwave." James relayed sadly. He had known one of the guys laying out there. And now he had another friend to bury and family to break the bad news too. "What's the plan Captain? If there are any survivors here what are we going to do? The Arks hundreds of thousands of light years away from Earth, it could be months before a friendly ship gets here."

"We can worry about that later Sergeant, for now; let's focus on finding any other survivors." Slipping his helmet back on Naruto checked both of the Marines in front of him as part of his squad. "Let's move out."

(On Board the Infinity)

"Admiral Lasky."

Lasky saluted as the Fleet Admiral of the UNSC Terrence Hood addressed him. Half out of discipline but mostly out of the respect he felt for the man who had gotten humanity through the Great War. "Lord Hood."

"I'm not going to sugar coat it Admiral, whatever this Warden Eternal is up to is causing the UNSC a lot of problems. At the top of the list is the portal from the Earth to the Ark. Hours ago it collapsed cutting us off from the research team." Admiral Hood said shaking his head. "Good men and women are trapped out there in the middle of nowhere, possibly at the mercy of Prometheans and there isn't a damn thing we can do about it."

"Sir, is the Infinity being sent to the Ark?" Lasky asked. The Infinity was the pinnacle of humanity engineering and with a Forerunner slip space drive in her she was the fastest ship they had but even then it would take months for them to reach the Ark. And by that time.

"It would be too late." Admiral Hood finished thinking the same thing.
"We can't waste an asset like the Infinity on the off chance the researchers and their guards could survive that long. With the Warden on the loose, we need all hands on deck. What I need from the Infinity Admiral is to find the Warden and put him down. He is the top priority target for the entirety of the UNSC. There's no telling what kind of damage a Forerunner A.I is capable of, especially if he decides to go after the Halo's."

"We won't let you down sir."

"Good luck Infinity, Hood out."

Saluting again Lasky let his hand drop when the Fleet Admirals video cut off. He knew the Fleet Admiral was right but that still didn't make leaving good men and women to die when he had the power to do something. "Roland-"

"Cortana say is we can get her to a Shield World she can reenter the domain and possibly kick the Warden out. It's not a guarantee but right now it's the best shot we have got." Roland answered his World War II pilot avatar voice was somber knowing how bad the Admiral was going to take leaving the scientist alone on the Ark.
"Sir your orders."

"We head for Sanghelios, the Covenant have used Forerunner technology for millennia they've got to know the location of other Shield worlds. Or at least how to find them. And get me Cortana and the Master Chief."

(The Ark)

"Sir, doors locked," James said the panel under his hand glowing red. "I'm betting the survivors are in there."

Naruto motioned at the door. "Then knock, or try and get them on the radio."

While he waited for the Sergeant to contact the survivors Naruto looked around at the hallway they were in his eyes stopping on Corporal McMillan who was still shaking. He'd have to work on getting the rookie to not get so stressed in situations like this or someone was going to die.
"Rookie, this your first tour?'

"Yes, sir."

Before Naruto could continue the conversation a loud had all three of the Marines raising their rifles as the door slid opened revealing a squad of Marines on the other side. All holding Battle Rifles and wearing the standard Marine uniforms.

"A little warning would have been nice Sergeant," Naruto grumbled lowering his gun.

"Captain!" the squad of Marines jumped to salute when they saw who was standing outside the door. They had all heard the rumors that the hero ODST had been found on the Ark and alive no less.

"At ease marines. Are there any more survivors?"

"Yes, sir. We have two other squads guarding the scientists who are trying to get in contact with the other outposts." One of the Marines said stepping forward ahead of the others. "It's good to have you here Captain; a lot of the guys are confused and more than a little scared at what's going on."

Naruto nodded as James and McMillan visibly relaxed at the news, there shoulder dropping in relief. "Good, that's good. Lead the way, Marine."

"Yes, Sir."

Following after the squad of Marines Naruto kept silent as James and McMillan conversed with the others. He was happy that there were others survivors but only a few squad of Marines wouldn't be able to hold back the Prometheans Admiral Serin had debriefed him on. With devastating weapons that disintegrate the target and Forerunner metals that took entire clips of standard rounds to eat through. "We won't last long if they attack."

"In here Captain."

Entering the room the survivors were holed up in Naruto's eyes landed on the two injured Marines first. One had his helmet off and blood soaked bandages wrapped around his head and the other was using a pair of crutches her left foot twisted at an odd angle.

The Scientists were all hunched over a table in the middle of the room whispering rapidly between the five of them pointing every now and again at one of the holograms.

"Captain, oh thank god you're here. We need to leave." Isabel popped up on the holo-table closing down the other holograms around her, a terrified look on her face as the scientist around her started to complain about their studies being halted.

"Isabel bring our work back up, we need to find out why this is happening."

Naruto stepped forward looking down at the orange A.I. "Isabel, was it? What's going on?"

"There are Phantoms coming here. We only have a few minute before they arrive." Now almost hysterical Isabel began pacing the table. "What are we going to? By my calculations, we won't last more than ten minutes in a firefight."

"Phantoms?"

"How'd they get here?"

"Isabel, what do we do?"

"Everyone be silent." Naruto barked cutting off any more questions. "Isabel is right, we won't be able to fend off two Phantoms and whatever troops being carried inside. James, McMillan, take a squad and search for any workable vehicles we can use. Doctors transfer whatever you can and destroy what you can't. It's not a coincidence whoever is out there arrived right when the portal shut down."

James and McMillan promptly left the room the four Marines who had met them at the door following after them. The scientists, however, were not as accepting of his orders.

"Destroy! Do you know how valuable the research we do here is?" The lead Scientist asked incredulously his colleagues all nodding in agreement one even glaring at Naruto.

"No, but I can guess. And if it is even half as important as I think it is we can't let it fall into enemy hands." Naruto wasn't a scientist but he knew the power the Forerunners had held and anything pertaining to a race that had the power to wipe out all sentient life in the galaxy was dangerous.
"Get me moving doctors, Isabel you're coming with me."

Pulling the logistic A.I's chip from the table he placed it in the slot on his forearm protector the small screen usually used for controlling the radio in his helmet lighting up with Isabel's face.

"Guess it's a good thing I'm not a ship class A.I or whatever you're planning wouldn't work."

"UNSC protocol dictates that no A.I can fall into enemy hands. You will be safer with me." Naruto said switching off the external speakers on his helmet when as he talked to the A.I. It was true she would be safer with him but saying it out loud where the other Marines could hear would diminish their trust in him.

Switching the speakers back on he pointed at the table when none of the scientists had moved. "Get moving docs, you have until James and McMillan find us a ride out of here to get what you need."

"Isabel, what's the ETA on those Phantoms?"

Before Isabel could answer to loud thumps echoed through the room.

"They're already here, and two brutes just landed on the roof. The only way in from there is the service hatch in hallway B."

"I'll deal with the Brutes, the rest of you protect the Doctors. Isabel, send a message to the other outposts, let them know that we have hostiles on the Ark and to get what they can and head for the 'Will Of Fire'." Leaving the room Naruto hit the panel to lock the locked the door behind him as he made his way towards hallway B the heavy thuds of footsteps above him matching his own.

Moving through the base he couldn't help but feel something off about the situation. Whoever was here none of the security measures picked up a slip space rupture around the Ark so the intruders must have either used the portal collapsing as cover meaning they were the cause of it, or worse for they've been on the Ark and have been waiting for the right time to strike? "And the portal shutting down cutting off any hope for reinforcements was as good as any."

"Captain, the Brutes."

"Are right above us. Don't worry Isabel; I've dealt with a lot worse than two brutes." Naruto tightened his grip on his rifle ducking into a room four doors down from the service hatch. Aiming down the hallway he waited with baited breath as the first brute dropped down followed seconds after by the second.

"Captain." Isabel's voice trembled at the sight of the hulking beasts at the end of the hallway.

Standing two feet taller than him and covered in black and red armor with sharpened spikes extending from the shoulders and forearms the two looked more dangerous than the brutes he had fought during the war that usually didn't have armor at all. In their hands was the Type-25 Covenant 'Spiker' rifle.

"At least they don't have helmets." He thought as he put the second brutes head in his sights. Squeezing the trigger the brute's shields flared but didn't last long under the concentrated fire and multiple rounds from Naruto's rifle entered its head sending blood splattering the walls and the other brute.

Ducking back into cover to reload Naruto heard the resounding thump of the dead brute's body hitting the floor followed by a deafening roar of rage and even louder thumps.

"Captain grenade!"

"I see it, Isabel," Naruto grunted rolling out of the room escaping the glowing blue orb that grew consuming everything it touched in a blaze of plasma. Now in the hallway, he moved to his knees getting ready to sprint for whatever cover he could find as spikes started flying over his head.

"Stay down Captain." Isabel's voice screamed in his ear.

Doing as he was told Naruto hit the floor again barely dodging the bottom side of the spike rifle taking his head off. Leaping forward he dropped his rifle wrapping his arms around the brutes waist tackling the alien to the ground.

Cursing as his helmet visor slammed against a ridge of the brute's armor cracking in the process he pushed himself up with one arm drawing his sidearm with the other.

"Filthy humapmph!"

Sticking the barrel of his pistol in the brute's mouth bypassing its shields he pulled the trigger repeatedly sending five rounds of M228-SAP-HP bullets into the brutes brain.

"That...That was brutal." Isabel said seeing everything through Naruto's helmet cam.

"You've never seen combat have you, Isabel?" Naruto asked as the adrenaline from the fight started to fade. Wiping the blood and brute brain matter from his pistol he placed it back at his side, picking his rifle back up.

"No, no I'm a logistics A.I., combat isn't my forte. I've heard the stories about the Great War from some of the veterans when they talked about it but it never sounded like that. Anyway, let's just get back to the others."

Naruto nodded as James's voice came over the comms letting him know everyone was on their way to the Pelicans and Warthogs that were still intact.

"Captain, hurry, more troops are landing at the front of the base."

Picking his speed up Naruto began sprinting through the halls towards the control center. There was still one more thing to do before he could leave."

"Captain, one of the Dr. Ramirez already set the self-destruction sequence. You need to leave now."

"Copy that, Isabel." Changing course Naruto headed for the gathered IFF tags on his HUD. It was good to hear the Scientist had gotten their act together in the past five minutes. But still, he couldn't shake the feeling that something still wasn't right. "Have the Phantoms made any moves to go after the Pelicans?"

"No, Captain they are holding position at the front of the outpost." Isabel relayed watching the two hovering alien ships through the security cameras. "Is that strange?"

"Very strange," Naruto answered as he exited the base. Outside two Pelican drop ships hovered off ground a few feet but the Warthogs were nowhere to be seen. "Where are the Warthogs?"

"Scientist went ahead. Didn't want them airborne in case one of those Phantoms was feeling Froggy." James said extending an arm to help pull Naruto into the Pelican.
"Looks like you took a beating, Captain."

Naruto waved off the concerns taking James offered hand. "Not really, was just little unlucky that's all. Did you get a hold of anyone from the other outposts?"

"No, sir but the patrol teams are on their way to the "Will" right now. Any idea on who that was back there, Captain?"

"I've been asleep for awhile Sergeant, not really caught up with the times yet." Naruto looked down at the base as more Phantoms and Spirits arrived carrying troops. "At least we'll get a few when the base blows."

"At least we'll get a few when the base blows." He thought as he waited for the fireworks to start. Even with their superior shields, the troops in and around the base wouldn't be able to survive the blast.

Frowning after two minutes passed and nothing happened he looked to the others behind him their faces mirroring his own confused look. "Isabel, why hasn't the base blown? A self-destruct sequence is set for two minutes; it's been two and a half."

"Maybe the Doctor set the timer for longer so we had time to get out."

Isabel said it but Naruto could hear in her voice she didn't mean the words she was speaking. Doctor Ramirez was the one who glared at him when he ordered them to destroy their work.
"Pilot, double time it. I want to be at the 'Will Of Fire' before the others!" He yelled up to the cockpit.

"Captain what's going on?" James asked grabbing onto his seat as the pelican jolted forward.

"One of the scientists is a traitor. When we get to the ship I want him in the brig." Naruto growled staring at the still intact UNSC base.

('Will Of Fire' Crash site)

Ramirez was one of the younger doctors sent to the Ark to study the Forerunner technology. A child prodigy smarter than his entire class only held back by his lack of focus. Until the UNSC had asked him to head to the biggest space station in the galaxy and study ancient technology. It had been a dream come true and after months of work, he would not let it all be for naught. "Even if I have to spend months in this cage."

"Do you have anything to say for yourself, doctor?" Naruto looked down at the brown haired man only a few years older than himself behind the bars of the 'Will Of Fires' jail cell. "

"All our work, months of studying would have been lost. What I did saved our work."

Naruto didn't speak as the doctor continued whispered muttering about UNSC protocols not taking everything into account and how when they got the base back they wouldn't have to start researching from scratch again.
"We aren't getting the base back doctor. You just handed over whatever the other doctors who actually listened to orders could grab while you what? Went and stood in the control room and stood instead of helping."

"If we mount and offensive and attack the base I'm sure we could get it back," Ramirez said confidently.

Naruto shook his head as James knocked on the door frame waving him over. Looking back at the doctor one last time he turned away leaving the traitor alone. He had nothing else to say to someone who would put everyone on this installation at risk for personal reasons.

"What's the verdict Sergeant?" He asked stepping out of the brig letting the doors close behind him.

While he dealt with the traitorous doctor he had tasked James and Isabel to inventory what they had left on the ship to use.

"Not much Captain. Only one reactor is online so we are half power, the scientists think they might be able to get the other working but I wouldn't hold my breath. As for weapons, the armory is still intact so we are good on that front. We got three Scorpion tanks, four Pelicans and five Warthogs. Not much for a Frigate but we don't exactly have a full crew. Isabel still going through the rest but she won't be long." James reported fidgeting as the two Marines walked down the halls of the crashed ship.

"You want to ask me something," Naruto said when James stopped his report. At James surprised look he explained. "You keep fidgeting."

"Those aliens had to get here on a ship and at their smallest Covenant ships carried thousands of crew members. We're outnumbered fifty to one. How are we going to win against those odds?"

"Together," Naruto answered his second in command.

"We'll lose."

"Then we'll do that together too."

And that is the end of this chapter. Hope you guys enjoyed. Leave a review letting me know.

As for the small Infinity part, there will be a few of those in most chapters nothing too major but enough to keep everyone knowing what's going on outside the Ark.

Thanks for reading everyone!"
