Fallout - TRIPS

Bethesda owns both Fallout and Doom, so basically you just described a crossover that could officially happen.

Fallout 5 should start in vault 666 and when you leave the vault instead of a land devastated by nuclear war you find yourself literally in Hell.

The final boss would be Robo-Satan and depending on your karma you either cleanse the souls of Hell and send them to heaven or you just take it over.
