Also, as far as I am aware, there are multiple rumors going around that if you own Arkham Knight before they fix the game and re-release it for PC you will either get a free season pass for the game or you will get a free Warner Bros. game.
Also I have no real way of being sure that redeeming this key for Arkham Knight after they have already taken the game off the stores will still secure you the season pass/game. But hey, there's always that chance that you can get $30 worth of DLC for free for a game that is going to be pretty good once it gets fixed.
