UAC Mars Base

This article or section needs cleaning up. Please edit it to a higher standard of quality.

UAC Mars Base is a UAC facility located on Mars. It is mentioned in Doom, Doom 2, Doom 3, Resurrection of Evil, Doom Resurrection, Doom RPG/II, Doom 64 Remaster, Doom (2016) and Doom Eternal.

Background

Doom/Ultimate Doom

Mars Base is the home of some of UAC's radioactive waste facilities. The Marine was stationed there for three years before being deployed to Phobos, where it's invaded by Demons.

Doom 2

The Mars base is soon fell under attack where every human being were killed except the Marine, who single-handedly stopped the invasion.

Back at last. After days of hard fighting in space, you've returned home on well-earned leave. You're one of Earth's crack soldiers, hard-bitten, tough, and heavily-armed. When the alien invasion struck Mars, you were the first on the scene. By killing, killing, and killing, you won. You stopped the invasion, saved Mars base, and became a war hero. What they don't talk about so much is that you were the only survivor. But that's all behind you now. You've quit the military, and are heading home. Your drop pod lands with a crunch. You open 'er up and look out. Damn! The city ahead is on fire. What the devil is going on? You stagger forward, clutching at your sidearm. Packs of refugees are fleeing the flaming metropolis. A band of them shriek in terror. You squint. What's that? Someone is attacking the refugees. You rush up and blast away, killing the troublemaker. It looks like a human but something's wrong. His mouth is filled with half-chewed flesh, and he's all messed up, like a zombie from a bad horror movie. Hell, not again! You can feel it. It's all starting again, just like on Mars. First, people are taken over, turned into cannibal Things. Then the real horror starts, the deformed monstrosities from Outside. But now it's on Earth!

Situation Analysis:

After days of fighting in space, you've returned to Earth only to find the situation is no better than it was on Mars. In fact, it's worse. The hell-spawned hordes are everywhere. Billions are dead. The few remaining survivors have planned to travel into space and save what's left of the human race. Unfortunately, the Earth's only transport has been taken over by flesh-eating mutants. You have to go back in action. Otherwise, humanity is history.

Doom (SNES/PSX)

An image showing Mars reveals that a large section of the planet has apparently been colonized.

Doom I Enhanced

The Doom I Enhanced release makes reference to the UAC Mars Research Facilities similar to Doom 3. It re-imagines Episode 1 as taking place on Mars.

You're a marine--one of Earth's best--recently assigned to the Union Aerospace Corporation (UAC) research facility on Mars. When an experiment malfunctions and creates a portal to Hell, the base is overrun by blood-thirsty demons. You must shoot your way out to survive.

Doom 64 Remaster

The Doom 64 Remaster Story mentions Mars research facilities base (similar to the Doom II manual, Doom 3, Resurrection and Doom RPG, and original doom manual):

Years have passed since you stopped Hell’s invasion of Earth. Quarantined for humanity’s safety, the UAC research facilities on Mars were abandoned and forgotten...until now. A signal from a degraded satellite suggests a single entity remains, and it has the power to resurrect the demons. As the only surviving marine who fought Hell’s forces, you are sent on a lone crusade to hunt down the Mother of Demons and stop a renewed demonic invasion.

Note: The original N64 game was set on Phobos and was more of a sequel to ending of SNES Doom (see Doom 64 timeline and Doom 64: The Story So Far (N64)).

Resurrection of Evil

It has been almost 2 years since the mysterious incident shut down the UAC base on Mars. Several months ago, one of the UAC satellites still monitoring the red planet detected a beacon originating from Site 1. This early research facility was long forgotten, even before the invasion. Now, you're a Marine combat engineer, part of the massive research and security team lead by Dr. Elizabeth McNeil. Your team is being sent back to Mars in an attempt to find and investigate the source of this strange signal. What you'll find, nobody knows, but hopefully it will offer new insight into the ancient civilization that once inhabited Mars. As your transport nears the surface, you cannot help but wonder what type of "accident" could have killed so many years ago... and could it happen again?

Quake Arena

The last transmission from Doom to Earth from Mars was, "They're all dead, every last fraggin' one of 'em." Everything after that was just unintelligible screaming. When the team from Earth finally did set down on Mars, all they found were the remains of the marine strike team and researchers. There were no demons remaining. There was also no trace of Doom. The Arena Masters had claimed him as one of their own.

One of the original combatants in the Arena Eternal, Captain Eldon "Phobos" Brock has been fighting for a long time. This marine led the return of troops to the demon-plagued Mars base, where his mission was to destroy any last vestiges of the demon infestation. Unfortunately, Phobos learned all too quickly that the rest of his team had other orders. His new mission is to survive in the Arena Eternal, which means he'll be doing his best to kill you and anyone else who gets in his way. Phobos loves the rocket launcher, and he's also prone to go for a railgun when there's one in the area. He also prefers getting a haste icon above almost any other item, when one becomes available. Phobos is more than a little paranoid, and this tends to show up in his comments during the battle.

Note: In the manual for Quake 3 the setting was actually Phobos rather than Mars base.

Behind the scenes

The manual for Doom II tells of a completely different set of events than occur in both the endings of the original Doom or Ultimate Doom which took place on Phobos and Deimos instead, and lead to the Marine in those games teleporting to Earth through gateways.

Some Fanon believe this to mean that the marines in Doom 1 and Doom 2 are completely different individuals who reached Earth by different means (Mars hero by drop ship, and the Phobos/Deimos marine by teleportation). With one hero having battled on mars and the other battled through Phobos and Deimos instead.

To add to the confusion some of the later manuals and websites also suggest that the marines in Doom 1, 2, 3 (and sometimes those of Resurrection of Evil and The Lost Mission) are the same character. At the very least most sources indicate that the marine from Doom and Doom 3 are the same.

It is possible that after arriving on Earth, the marine was sent back to Mars. This would likely mean that Thy Flesh Consumed took place after his return to Earth on the Dropship and before Doom II started, rather than right after Inferno. If the marine from Doom 3 is the same as well, than it's possible that Doom 3 is actually telling the story of the marine's return to Mars post inferno.

Who knows we but the differences in these characters might have inspired characters such as Doom (character) and Phobos (character), B.J. Blazkowicz III and Stan Blazkowicz as separate characters in Quake and Doom RPG respectively.
