A Left 4 Dead/Back 4 Blood type of FPS PvE game.
Unfortunately Dead 4 Returns is assumed dead since the abrupt complete silence and no news, but I still think there’s a huge missing opportunity to be made here to create a great CO-OP PvE game like those in the title here. Obviously needs to be both iOS and Android, maybe even PC,no hyper casual bs, a full fledge AA or AAA game, I think the right team with enough talent and resources could pull it off.
