Just use the new engine to remake Brutal Doom. Bam, it's good to go.
The using limbs as keycards thing could be horrible. The rest sounds fine. Except naming it just Doom again, I really wish they would stop that shit. Give it a subtitle or something so we aren't saying shit like Sonic 2k6, Prince of Persia 2k8, and Tomb Raider Reboot just so that people know what the fuck we're referring to. Shit, go nuts with it. Doom: Son of Doom in Monster World.
