Achievements! It was just our roundabout way of saying Batman: Arkham City will support Games for Windows Live on PC, according to a Warner Bros. rep speaking to VG 247 today. We assume, just like its predecessor, the game will also be sold through Steam, though there has yet to be a games page created for it. We've contacted Warner Bros. for clarification. Achievements and DRM for Arkham City will be handled by Microsoft's platform.
