https://www.myabandonware.com/game/you-are-empty-f1j
essentially a Painkiller copy set in 1950's Russia, after mind control experiment turns everyone in the USSR into a monster and you have to fight to survive
has a very cool level design based on real Russian cities and architecture but it's an early 2000's FPS so it's a bit jank
