What versions of XBox will work for the game? and do I launch the game from the XBox or computer?
BlueBerryBandit the game is PC only, when they said Xbox they were referring to the controller not the console. The game is only local coop, meaning you have to be on the same PC just with a controller plugged into it for each player.
EDIT: I do believe that they is working on a PS4 and Xbox version if they get what they need for it.
