Okay I will give you a list of really great coop games in my opinion. Garrys Mod, Dead Island, Dead Island Riptide, Dying Light, DayZ, Arma 3, Ark Survival, Payday, Borderlands 2, Raft, 7 Days To Die, TruckersMP(Euro Truck 2/ American Truck Simulator), Just Cause 3, MTA SA, SAMP, Squad, Storm Works(Requires very High End PC) and Grand Theft Auto V. Here are all the COOP/Multiplayer games I could think of. There are some more but cant remember. Hope this could help you.
