In the future, mega-conglomerate, The Union
Aerospace Corporation has expanded to Mars and its moons, Phobos and Deimos, establishing
some super shady laboratories and a strong military presence, just in case. As UAC experimented
with teleportation, they developed dimensional gateways and opened a gateway to actual hell.
Eventually, one scientist, Dr. Olivia Pierce, made a deal with the devil. Pierce and the UAC scientists enhanced the
demons, integrating powerful weaponry and even jetpacks into their demon-flesh. They
even forcibly possessed humans to become cannon fodder in the upcoming invasion, then Dr.
Pierce opened the gate and demon’s flooded the base. She had sold out humanity to usher
in a hellish new age or something. But Dr. Pierce and Satan forgot about Doomguy
who was taking a nap in a nearby bunker. As everyone’s favorite one-dimensional space
marine protagonist, you’ll fight through the UAC base and take the fight to hell as you
show Cyberdemons that real bad asses don’t make plans, they run around in circles with
a chainsaw stomping their enemies faces into the dirt. So throw on a helmet and dust off
your BFG because you don’t need a great story to feed a demon its own heart before it explodes. Have fun!
