soon-to-be-shuttered Games for Windows Live platform in favor of Steam's collection of similar features and copy protection.
GFWL copy protection and features (including achievements) have been removed from both Batman: Arkham Asylum and Batman: Arkham City. The upgraded Steam versions now include Steam Achievements, cloud support, Big Picture support, full controller support and Steam Trading Cards.
"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," an announcement on Steam detailed. Steam users report a free upgrade to the GOTY editions of each title upon registering their CD key in Steam. Switching to a new copy protection system means that players will be forced to restart the game as saves rooted in the GFWL platform are not compatible with Steam.
This weekend, both Batman games are available for 75% off to celebrate The Dark Knight's upgrade to the industry's preferred PC platform.
