Sorry for the long update, anyway I do not own Doom or Mass Effect, Doom belongs to Id Software and Mass Effect belongs to Bioware. _

1 hour later….

Commander Victor Shepard sat at his desk with a cup of coffee at his side, recapping past events and checking for mail. 2 weeks ago, he and his team went on a suicide to the collector base through the omega 4 relay and defeating them, and all of them (including the Normandy crew that was captured by the collectors) came out alive, Shepard even left the collector base to The Illusive Man so that they could find a way to beat the Reapers.

He then remembered what happened a week before, Admiral Hackett at assigned him a task of rescuing Doctor Amanda Kenson from batarians who had captured her. Shepard was to go in alone and rescue her (Which he succeeds in doing). After rescuing her, she took to the project base, where she betrayed him and had him imprisoned. Shepard managed to escape and started up the asteroid and crashed it into Bahak mass relay, killing Doctor Kenson and the batarians in the system. Later, Hackett later came onto the Normandy to debrief in person, telling him that the batarians would want blood for what happened and saying that he would eventually have to go to Earth and face the music, Which Shepard found unbelievable, he just delayed a Reaper invasion, they should be thanking him for fucks sake.

Shepard then let out a huge yawn, he hadn't slept in days, all because of those nightmares he's been having. It started three days ago, Shepard would find himself chained to a rock wall, witched stretched him out right, and then very slowly, a huge spike would pierce through him, unleashing an unbearable pain, but that's not all that happened, it also brought back painful memories, first it would bring the time he let his unit get killed on Torfan, the time he left Ashley Williams behind on Virmire, and the time he died. He tried his best not to scream, but it was too painful not to scream. But it wasn't only that, one time he was chained by the waist upside down, slowly being taken down to a pool of lava, and after about ten excruciating seconds in the lava, he woke up with cold sweat pouring down his forehead. He tried getting sedatives from Doctor Chakwas, but not even that helped, he still had the dreams and woke up with cold sweat, these were not normal nightmares, and Shepard knew that.

"Message coming in from Anderson Commander, he says it's urgent." Joker said over the comm. Shepard groaned, what did Anderson want so badly this early in the morning? Groaning again, Shepard opened the vid comm and Andersons face appeared.

"Good Morning Shepard." Anderson said

"Morning Anderson." Shepard said in a what-the-hell-do-you-want tone.

"Sorry to bother you so early in the morning, but we have a situation." Anderson said "Shepard, you're familiar with the UAC right?" Anderson asked.

"The Union Aerospace Corporation? The Alliances biggest sponsor, yeah why?" Shepard asked

"Well, we lost contact with their base on Mars." Anderson said

"So?" Shepard asked

"Well, I think that they were invaded." Anderson said

"Who do you think invaded them?" Shepard asked

"The Batarians, no doubt this is a response for blowing up the Mass Relay." Anderson replied

"So why doesn't the Alliance send in a fleet or something?" Shepard asked

"Udina and the rest of the council are trying to keep this silent; they think that this is some kind of communications disruption." Anderson said

"But you think otherwise." Shepard said

"Yes, I think the Bavarians have declared war on us, and I want you to go to Mars and stop them from reaching Earth." Anderson said. Shepard knew he was right, the batarians had no doubt declared war on the Alliance, and there first action of war was to attack one of the UAC's bases, and if that was the case, Shepard had to get to Mars fast!

"Alright, I'll head to Mars right away." Shepard said

"Good, and tell me what you find, Anderson out." And with that, Anderson disconnected. Wasting no time Shepard said over the comm "Joker, tell the team to meet in the briefing room, and set a course for Mars."

"Aye aye commander." Joker replied. The got up with his coffee, went into his private bathroom and emptied it into his toilet and flushing it, then he but the coffee cup back on his, then he headed over to the elevator, pressed two, and the elevator began to descend.

1 hour earlier….

Marlowe slowly got out of the elevator with his shotgun ready. Scanning his environments and wishing this shotgun had a flashlight on it. After a few moments, thinking the area was clear, lowered his gun, only to be attacked by a human Z-Sec that came out behind a box and opened fire on him, Marlowe quickly ducked behind a couple of boxes, waiting for his adversary to reload. When he heard the gun fire stop, he peaked out of cover to see the Z-Sec reloading; Marlowe quickly pulled out his machine gun and opened fire, dropping the gun-wielding zombie. Taking in a deep breathe, Marlowe pressed on, climbing up a ladder. Marlowe was then greeted by a quarian maintenance worker.

"You're not one of them?" He asked

"No, are you alright?" Marlowe asked

"Yeah I'm fine." He replied, after a few moments the quarian asked "Do you know what happened?"

"No idea, I'm on my way back to Marine Command, want to come with me?" Marlowe asked

"No, I feel much safer up here." The quarian replied. Marlowe, think the worker wouldn't survive long without some firepower, pulled out his pistol and handed it to the quarian, not before twirling it in his hand.

"Here, take this you won't survive long without it." Marlowe said as the worker took the gun.

"Thanks, but don't worry about me, I've been in tighter situations." The quarian said

"Alright, take care of yourself." Marlowe said as he pressed on.

On the way through the vents, Marlowe reached multiple dead ends, finally coming to a hole, dropping down; Marlowe was attacked by a turian zombie, who tried to swipe at him with his razor sharp talons. The zombie managed to get a good swipe across Marlowe's right cheek. Marlowe, now with blood pouring the right side of his face, pulled out his shotgun, shoved it right into the turians gut and pulled the trigger witch in a fraction of a second, blood , bits, and pieces were shoot out the zombies back.

It took a few moments for the pain in his cheek to kick in, and boy did it hurt. Marlowe pushed pressure on his, it wasn't that deep enough to create a hole, but it still hurt. Marlowe looked around at his environment, of all his luck he was in the medical bay, Marlowe than began to check to see if they had any med-gel, after 2 minutes of searching, he found some in a cabinet and began applying it to his cheek, the pain soon began to dull and he began to press on, on the way to Marine HQ, he encountered at least 14 of those grey creatures and 19 zombies/Z-Secs, all of which nearly took him down, and he found another pistol along the way.

"Excellent, now all I need is a second one." Marlowe thought as he pressed on to Marine HQ.

"Marine, what's your status?" Asked Kelly over his comm. Marlowe put two fingers up to his ear and said "Progress is good so far sir; I'll be at HQ momentarily."

"Good, but pick up the pace, over and out." Kelly said as the elevator stopped and opened. Marlowe took about 2 steps before he heard voices coming from an air vent above him.

"Your way in over your head Betruger, the situation is out of control." Said one voice, which he recognized as Swans.

"Nonsense Swan, everything is under control." Said another voice witch he recognized as Betrugers

"As much as I would like to believe you Betruger, I'm afraid were going to need the Alliance's help for this." Said Swan

"I said I have the situation under, and we definitely don't need the Alliance's help. Now I hope you understand when I say that I have the situation under control, Betruger out."

After a few moments, He heard Swan say, "Yes, we understand, right Jack?"

"Yes" Jack said as he opened his briefcase, witch content glowed green "We fully understand." But before he could hear what they were going to say next, 2 more of those grey creatures came out of no-where.

Quickly surveying the area he found no source of cover, so he decided to dodge there attacks. One threw a fireball at his head but he dodged it by inches, the second one hit him square in the chest knocking him back over, the creatures advanced on him, but Marlowe quickly pulled out his shotgun and blew two holes in both creatures.

Sweating, Marlowe got up, looked around and pressed on eventually reaching Marine HQ and approaching the video screen in front of him

"Sargent Kelly, this is Corporal Marlowe, are you there?" He asked. Kelly's face appeared on screen.

"Marine, glad to see you're alive, I have a new objective for you. You're to link up with Bravo squad to send out a distress call to the Alliance." He said

"Is it that bad sir?" Marlowe asked

"We don't know what were up against Corporal, and we don't have the manpower to fight, we need the Alliances help for this." Kelly said

"Alright, I'm headed to their location now." Marlowe said

"Good and keep me informed, Kelly out." Kelly said, as the video screen went blank.

Marlowe pressed on, reaching the bathroom he passed by earlier, he really wanted to wash his face. So he entered the bathroom and went to the sink and turned it on, splashing some cold water on his face.

As he looked up into the mirror, everything just went red and it felt like his eyes had zoomed into the mirror, flames were behind him and the water on his face turned into blood, but the worst part was that his face was decaying and was becoming more bone than meat. But quickly it all stopped, leaving Marlowe stunned.

He didn't have to to take deep breaths because another one of those grey creatures appeared outside the bathroom and attacked him, but Marlowe was quicker, pulling his shotgun back out and filling the creature with led. Marlowe toke some deep breaths and said "What the fuck is going on around here?"

He shook this off and pressed on.
