Dear Batman Arkham Fans - Microsoft has begun the process of closing down Windows Live services over the next year. To make sure there is no interrupted service, we will be moving the game to Steam for verification and update services for both the Base and GOTY versions of Batman Arkham Asylum and Batman Arkham City.
If you purchased either of the games on Steam all you have to do is let Steam download the latest patch and you will be fine.
If you purchased the games somewhere else you will need to enter the code in Steam. (You can find steps to do this on the bottom of this.
Unfortunately, you will not be able to continue playing from your current save. You will need to start a new game.
Going forward you do not have to worry about where you stored that disc. If you switch computers or go to a friend’s house you simply need to download Steam, log into your account, then go to the library and select to install your game.
