I do not own Doom or Mass Effect, Doom belongs to Id Software and Mass Effect belongs to Bioware

Marlowe walked out of the kitchen to find the sentry bot still waiting for him and when he approached it it walked away from him, apparently wanting him to follow him again. Marlowe followed it to the security checkpoint where it went to a little square on the floor, laided down and shut itself down.

Marlowe went past the door and walked over to the elevator and went inside, he then pressed the transfer button and felt the elevator go down and then after 13 seconds it stopped and the doors opened and he walked over to the desk that was protected by bulletproof glass with a marine behind it.

"Welcome to the dungeon marine." He said "The most un-exciting place on mars, I'm goanna need you to grab some armor and a pistol before I can pass you through security." Marlowe than walked over to the where the pistol and armor were. "Alright grab your gear." He said.

The Bulletproof glass then slided up and Marlowe grabbed the armor and put it on and then grabbed the pistol.

"Now your ready for combat, now let me do a radio test." He said as he walked over to another terminal and then he heard his radio go on with his voice over it

"Mars sec radio check, alright everything checks out." He said and Marlowe gave a nod "Looks like you've been assigned to the decomishied comm facility just follow the passage through the underground junction and straight out, you'll have a quick evac, and besides, there's no better way to see the martian surface than to run across it." The door than opened "Okay your all set." He said as Marlowe walked through the door "Oh yeah and keep in mind that civilian's are working down here, so don't get excited and shoot any." The marine said over the radio.

Marlowe walked down some stair cases and past a few people and on the way he ran into maintenance guy who said to him "Hey, your looking for the missing scientist right?" He asked.

"Yeah why?" Marlowe asked him.

"I'm not sure you want to find him, you see….eh never mind." He said, this made Marlowe feel a little uneasy, why didn't that guy want him to find the missing scientist? He then shook this thought off and focused on the objective at hand and walked off. On the way he also passed a quarian and a human

"Listen Scotty, I've done this a million times its not that hard." The quarian said

"Why don't you crawl your quarian ass down here and do it yourself." The Human replied

"Okay number one, fuck you, and number two is because I'm getting paid to make sure you do it."

Marlowe than walked off through the tunnels where he found a salarian working on a bridge and when Marlowe approached him, he jumped "Geez! Do you make a habit of sneaking up on people, everyone's already on edge down here with all the strange things going on." He said before he continued working.

Marlowe than continued to walk down the tunnels when all of a sudden the lights went off and then went on a few seconds later "I see what that guy meant." Marlowe thought to himself before he walked to the end of the tunnel where he met another marine siting by the airlock.

"Hey you're that new guy headed for the old comm center right?" he asked and Marlowe nodded.

"Well just to let you know this passage doesn't go all the way there, you'll have a quick walk outside through the centers airlock, and hey don't sweat it, your suits got plenty of oxygen." He said

Marlowe nodded and proceed through the airlock and pushed the airlock sequence button and the door behind him closed and the door in front of him opened, showing the martian surface outside, Marlowe than took a deep breath and walked outside and the proceeded to the old comm facility, witch only took a few seconds to get to, he then proceed into the comm facilities airlock and pressed the airlock sequence button and proceeded inside. Where he walked over to a nearby elevator and then he heard the sarge over his radio "Marine this is Sargent Kelly, you need to double time it down there searched your assigned area and haul ass back to Mars City, out." He said, Marlowe than proceed down the elevator and through a passage where he soon found the missing scientist.

"Huh? No no please, you must let me get this communication out." He said

"Okay take it easy sir, just come with me and everything will be fine." Marlowe said

"No, they must be warned while there is still time, I can't let I can't- You don't know what I've seen you can't possibly comprehend….The devil is real, I know, I built his cage." He said

"Okay now your sounding crazy now step aw-" But Marlowe was cut off by someone on the radio

"I'm getting thermal readings here." He said followed by more radio chatter.

And all of a sudden the lights went out and the screen went blank, witch then was followed by weird and creepy noises, and then out of now where a light the shot up from the floor and spread around the room and then a skull went past his head with mad Marlowe jump back, witch was then followed by laughter, evil laughter. Then the weird light grabbed onto the scientist and then the scientist looked weird, he approached Marlowe and swung at him, witch Marlowe dodged.

"He calm down our I'll ge-" But than without warning the scientist lunged at him, and Marlowe, not even thinking, pulled out his gun and shot him straight through the head, ending the scientist's life.

"Oh shit." Marlowe said to himself but before he could do anything else the door opened and a marine appeared and began to shoot at him, Marlowe than ran for cover, breathing heavily.

"He listen he attacked me and-" but the marine continued to fire at him. Marlowe, deciding he won't listen to reason, reloaded and returned fire, it took a few shots before the marine went down.

It took Marlowe a moment to realize what he had just done

"Shit shit shit." Marlowe thought, he had just killed two people, but the attacked him. Marlowe wondered what would happen to him when he returned back to HQ, but then he heard Sargent Kelly over the radio, saying to head back to HQ and also saying that they were under attack by an unknown enemy force. He guess that whatever attacked Marlowe was part of what was attacking the base so he felt some relief but continued onward, on the way out of the comm facility he heard people over the radio, screaming for help and giving orders to fall back, Marlowe also encountered, what appeared to be a zombie and killed it. He then went to the airlock and proceed back to Mars City, where more zombies and hostile marines attacked him, he then made his way to the bridge where a fat zombie waited for him and Marlowe put him down, when Marlowe went to the doorway where he came in, a clawed arm shot through and retracted back through the doorway.

"What the hell?" Marlowe asked himself before he looked to his left and saw that the bridge had come down, making a new passage for.

"Better than what's ever behind that door." Marlowe said and went past the bridge where he encountered another hostile marine who Marlowe hand put down a few seconds later. On the way back to the elevator, Marlowe hand encountered more zombies and hostile marines (who he decided to nickname "Z-Secs") and had also picked up a shotgun on the way. He also encountered a grey creature that had the same clawed arms of the creature that shot its arm through the door he was previously by, the creature had shot fireballs and swiped at him with his clawed arms but Marlowe killed it with his shotgun. Marlowe continued to make his way back to the elevator; he encountered even more zombies, Z-Secs, and those grey creatures, the way the monsters were appearing kept Marlowe on his toes, one hand appeared right out of a wall, another appeared out of maintenance shaft, another appeared out of a staircase. Marlowe wondered where these monsters might appear next, as he made his way back to the security checkpoint, where he killed another Z-Sec and opened access to the elevator and weapon case, he went to the elevator, killed the grey creature that was there and picked up the machine gun and extra ammo, he then went into the elevator and proceed up to Mars City, to fight whatever was to come.
