I remember back in 2013-2015 (maybe), there was this FPS game with a PVP mode, where one squad was made by like red "monsters" with two black claws per "hand" and the other was made by simple soldiers, and there wasas a zombie mode too where you could use paintball guns.
I and my brother remember the game like this and that we played for hours, i don't now if it's an our mandela effect, but if it existed, please tell me
