A massive demonic invasion has overwhelmed the Union Aerospace Corporation's Mars Research Facility, leaving only chaos and horror in its wake. As one of only a few survivors, you must fight your way to hell and back against a horde of evil monsters.
Skyscraper for Doom 3 is an old set from 2010. This is the original single player version, not the Last Man Standing version which is presently here on moddb. This was again uploaded for archive purposes. Enjoy.
