There should be a zombie game mode where u start at a point like a or c and the players should have lives and the zombies have infinite lives like rush but there should be a time for the zombies like 20 min and once that goes out players win if the players lose all there lives then they lose the zombies should be npcs and there should be cars and helicopter no tanks some of this doesn't have to be in the game but i will love it and in will be good to have a pve
