The initials room in E2M7 bears the logo of a Doom WAD made by Tim Willits and Theresa Chasar - maybe that's the Doom reference? Or the demonic imagery in general? Hmmm...

Maybe Starship Troopers is actually referencing Quake II, since both are in the military sci-fi genre. But the movie definitely does not include any Lovecraftian gothic stuff or other dimensions. It's invasions of planets and killing giant bugs, mostly.
