Jason "heXum" McCord has released a single player map featuring custom monsters, models, music, textures and even custom voice overs.
PREMISE: While fighting your way out of the recently invaded UAC base, you find a door whose marquee reads "Executive Quarters". After a while of searching e-mails in your PDA you find the code to the locked door and let yourself in. The vice president of the UAC had just welcomed his family to the UAC base on Mars for a visit when the demonic invasion hit. You find his bloody body along with his PDA in the hallway to the visitor aircraft docking station. You learn that his wife and daughter might still be alive, but they are somewhere in the executive living quarters hiding from the monsters. You decide to take the time and search for them and hopefully send them back to Earth safely. This is where the map begins.
EXTRAS: The classic Quake monster "The Shambler" makes an ferocious entrance into Doom III compliments of Obi-Wan
