-The Master Chief has just left Earth on a new, strange, mission-
"If my coordinates are right, which they usually are, the structure we're looking for should be only 2 kilometers ahead." Cortana said in her casual voice, "Unless it's invisible it should be around here." She waited before adding, "Look. Over there. I'm picking up multiple heat frequencies right in front of us."
The Pelican shuttered as Chief looked out the back to see a massive building armed with cannons and things he couldn't tell what they were. He remembered fighting the Covenant on Jericho VII, when he had first encountered Hunters. They had been intimidating, but the Chief and his team had managed to beat them.
Now, he had a squad of ODSTs with him, code-named "Helljumpers". They were the elite UNSC division and Chief already knew how to work with them because of Halo. Their mission was to go in, find the prisoners stuck in the prison cells, gather as much intel as they could. Then, get the heck out of there before they got blown up. Easy, Chief thought.
He looked at his Helljumper squad. They consisted of a ragged looking sergeant, two privates, a second lieutenant, a first lieutenant, and two demo experts that, literally, looked like they'd been through hell once or twice. He had some tough, battle-hard and scarred, marines with him. The sergeant twisted uneasily in his seat and the Chief's HUD gave him his name, First Class Sergeant Ralph "Dicky" Dick. He had an amazing record and the Chief respected him immediately. He look at the others, Second Class Private Morgan Washburn; First Class Private Lupita Rosenta; Second Lieutenant Jazette "Falcon's Eye" Tempito; First Lieutenant Jim "BM" BcMenerim; First Class Demo Private Jonathan Lars; First Class Demo Private Owen Lars.
The Spartan looked out the back of the Pelican, Space. They neared the structure now, everyone starting to check that their weapons were loaded and locked. The sergeant made an elicit comment, looked at his Marines, and smiled. Those are his troops, Chief thought, Just like my Spartan-II brothers and sisters. The thought of his lost siblings lowered his spirits, but he knew he had to concentrate on the mission, so he turned his attention and listened to Cortana.
"Ok, once you get inside the structure, I'll get the mainframe of the building and mark the prison cells with nav points." She told him.
"Fair enough. How long will it take? I was really looking forward to coffee with Johnson today." He said with a slight grin.
"I'm not even going to answer that question."
The Master Chief turned his head to look out of the view point, the structure was in front of him. His stomach took a leap, this was some of the first action he'd seen since the end of the second Halo, but he was not any softer. The Pelican banked left and rose up into the structure, the Marines were ready, and so was the Chief. The aircraft stopped, landed, and everyone jumped out as the Pelican dusted. Sergeant Dicky rolled and Temito said, "Sir, was that really necessary, sir? You could've alerted the enemy of our prescence."
He answered back with a casual sense of humor, "No, but I though ya'll'd like a decent view of my-," he was interrupted as enemy fire hosed him down and burned holes in him, leaving the air with a burnt flesh smell. Well, so long for that Marine, the Chief thought grimly, now ducking behind some rocks for cover.
The Helljumpers were still alive, save that one idiot Sergeant. The Chief popped up and opened fire, dropping two Jackals and wounding an Elite. He lobbed a grenade into the mess, was rewarded with a scream, followed by a rain of flesh. BcMenerim gave the order to move up and all of them moved. The Spartan was extremely thankful for the venting system of his MJOLNIR armor because he knew that the ODSTs were experiencing a jack-load of disgusting smells.
Darth Vader walked through a hallway with his Stormtroopers, rounded a corner and found what he'd been looking for. There in the cells were the Rebel prisoners and he was going to kill every single one of them. He used the Force to break the shielding, but sensed something that made him jump. Someone else was on the structure and were in the hallway opposite of where he came. Vader waited for someone to pop out so he could throw his lightsaber at them, good target practice. He waited a while longer, but then decided to turn and start on the Rebel scum. The Sith Lord felt no remorse when he was about to kill the rebels, and struck the first one, sending his head toward the back of the chamber.
Chief waited, something wasn't right. He thought he'd heard noises, along with a click and the steady thump of armor. Covenant were in there now, he was certain. The Spartan took a deep breath, sliced-the-pie, and stuck his head out. He almost collapsed as he looked upon the scene, white-armored troops stood guard and an enormous black figure was killing the prisoners with a new Covenant sword. Oh great, just what I need before coffee. Two new Covie bastards to kill and a new sword. How much worse does it get? His question was answered as the corner he poked his head out was drenched with fire and he was forced to retreat. Crap, now they know where I am.
He jumped out and fired his Assault Rifle along with one grenade, as he attempted to save the prisoners. One of the white-armored troops took half a clip untouched, but flew as the grenade behind him detonated.
This was the start of a new battle.
Vader's "fun" was interrupted as an enemy jumped out from behind a corner and killed a Stormtrooper. He kept killing the Rebels though and used the Force to deflect incoming fire. As he finished off another scum-bag, a howl pierced the battle as three more 'Troopers fell. Whatever these new Rebel scum had come with, he knew he would leave none surviving. He flung his lightsaber out and watched as the red glow cut through two enemy soldiers.
This was the start of a new battle.
