Warner Bros. Games has patched Batman: Akham Asylum and Batman: Arkham City to remove Games for Windows Live and Securom from the PC versions of the games. Keys purchased through retail sources can be activated through Steam. Just like when BioShock 2 was updated to remove GFWL, everyone with a valid key will get the GOTY editions of these games with all the DLC!
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.
Both games are currently on sale through Steam to celebrate.
