Warner Bros. has detailed how the PC versions of Batman: Arkham Asylum and Batman: Arkham City will be migrated to Steam from the soon-to-be-closed Games for Windows Live.
The previously announced move applies to both the standard editions and game of the year re-releases.
As detailed in a Steam Community post, users who purchased their games through Steam will only need to download a patch.
Those who picked the games up on disc or via another digital retailer will need to input their CD key into Steam to proceed. Unfortunately, players will lose their current save progress and will have to start again.
You’ll only need to do that once, though; Warner Bros. pointed out unlike Games for Windows Live, Steam doesn’t require a CD for reinstallation, which is a blessing.
Sequel Batman: Arkham Origins will use Steamworks when it launches on PC at the end of the month. It’s also coming to PlayStation 3 and Xbox 360.
