"Suppressive Fire, On that door Now!" Tim Shouted as he ran behind the cover of a wall. The other two members of his squad sprayed the door with automatic fire. The grunts staggered back and fell puddling the floor in their blood. Tim glanced down the wall and found what he was looking for. A small pad, that locked the door. He slammed his fist into it, the door closed just as a pair of elites were about to breach their defense.

"You know that door isn't going to hold em." Said the Demolition Expert, Chris.

"Nah, you think. Anyhow we are going to the control center. Get that data and get the hell off here." Tim said while reloading his assault rifle.

The squad members nodded and Tim took point. They quickly ran down corridor after corridor until they ran into a Covenant squad. Tim quickly tossed a grenade into the surprised group of Covenant. Which comprised of an elite, jackals, and grunts. The grenade exploded killing a few jackals and grunts. Tim rolled and opened fire as soon as he was prone. The remaining jackals quickly doubled over. The elite roared in rage and charged. It mandibles opened, black shark like eyes ablaze and blood red amour glinted under the artificial lights of the corridor. Tim began to back step, the elite froze its energy shields flared and overloaded as Chris showered the alien.

Kyle subsequently ran up to the elite, pistol in hand and emptied a clip into its elongated head. Kyle laughed and shot the dead body some more before the squad formed up. Kyle was the sniper of the team, also the most outspoken person of the squad. Tim used hand motions for them to fall back into positions. They rounderd a few more hallways and stopped a thick Titanium door. Next to it was an keypad on the wall, like the one earlier. Expect this one had security, and Tim needed through.

"Kyle, hack this door, and hurry." Tim commanded as he stepped aside and let Kyle come through.

"Sure, Just a minute." Kyle said as he pulled out a small laptop and furiously tapped at the keyboard.

"There." He murmured as he closed the laptop and stored it away in his backpack. The grey door quietly slid apart and allowed the squad to go through. The room was large, filled with computer monitors, scientific data and other contraptions Tim didn't recognize. The team quickly cleared the room and slowly walked towards the center and what appeared to be the main computer.

"Kyle, hack the system close all door between us and the Covenant, then grab the data. Understood."Tim barked as he stared at the room before him. The circular room seemed to be clustered with old run down junk. Hard to believe this was one of the UNSC most important research facilities

"Uh, Tim, Chris, check this out." Said Kyle in a curious tone. The two of them walked towards Kyle. In front of them sat on a desk an large computer, about the size of the ones on the frigates. There was a slight buzzing sound and a light was emitted from a cylinder like object from the side. Curious Chris stepped fourth and watched as a three foot figure appeared. Dark red, and transparent appeared a Roman solider. Spear held in his left hand and a red cape draped over his back. The squad recognized what it was an AI.

"Who are you?" The AI demanded raising its holographic spear. Tim stood his ground and slung his rifle on his back.

"We are Spartan Grey Team, Here to prevent the Covenant from gaining UNSC top data." Spoke Tim as he watched the AI.

The Roman Solider sighed.

"So the Covenant has been hacking into my systems...Hang on;" The AI disappeared and reappeared, worry on his face, "We've got to go! Take me with you and I'll get us out of here. Now!"

Tim moved forward and ejected the data crystal for the AI. He fumbled around the back of his neck and slid in the crystal into the slot at the base of his neck. An odd sensation filled his head, as if a warm liquid were being poured into his brain. He had heard rumors from other Spartans that every AI had different feeling as they inserted into them.

"By, the way, My name is Octavian." Whispered the AI in Tim's head. He shook trying to clear his head and glanced around the room. The room shook and shook again a loud noise could be heard outside the room.

"Chris arm those nukes, leave them here and hidden. Set time for Three minutes." Tim ordered as he readied his assault rifle. Chris hid the nukes under a nearby desk. A small timer appeared in Tim's HUD.

"Octavian, show me a way out."Tim yelled a nav arrow appeared a few hundred meters away.

"Through those doors, I'll open the doors as we get to them." Said Octavian coldly.

A loud explosion sounded behind them and group of elites scrambled inside the room. Kyle turned towards them and opened fire. The elites rolled and hid behind desks and fired back. A few bolts hit Chris and his shields were faltering.

"We don't have time for this. Chris drop an Lotus mine. Now!" Tim ordered as he coved Chris. Kyle and Tim stood on both sides of Chris, dishing out lead trying to suppress the elites.

"Done" Chris said and Stood up. The three ran and ran through door after door. A jaw wrenching explosion shook through them as the mine went off. Just ahead was the outside, Tim sprinted. His legs working faster than any normal human's. He glanced sideways and saw his squad keeping pace. Sun light reflecting off their olive green MJOLNIR Mark V amour. Up ahead was pelican in a patch of a field. Tim sprinted and gave more energy to running.

Tim cursed in surprise as pair of hunters stepped in front of the pelican. The giant creatures hid behind their impeccable shields. Their fuel rod mounted canon began to glow a bright plasma green. They fired, Tim rolled left and got to his feet as fast as he could. The hunter pair turned and raised their shields. Tim back stepped firing all of his ammo into the blue armored creatures. Crack, Crack a trial of white smoke hung in the air. Both pairs dropped dead. Kyle reloaded his S2 AM sniper rifle. Kyle ran towards Tim's location, and Chris brought up the rear. They quickly entered the pelican.

Kyle furiously worked the pelican. The stubby Dropships rose and gathered speed and began its ascend into the atmosphere.Tim and Chris settled into the harness of the troop bay. A ear defying detonation of the nukes, yielded an large blood red, then orange nuclear mushroom cloud. Its high speed winds tossed the pelican for a breif moment. The research center that stood there was gone, for all its vaule wasted because of the damn Covenant. Tim opened up his com to his team.

"Job well done, boys. Lets head home."
