The tumor that is Games For Windows Live has now been excised from another game - two games, in fact. Following the welcome news that BioShock 2 had been cured of its reliance (opens in new tab) on Microsoft's insidious service, both Batman: Arkham Asylum (opens in new tab) and Arkham City have undergone successful surgery (opens in new tab) , swapping GFWL for the much less awful Steamworks. In honor of being free at last, the games have been given a 75% price cut (opens in new tab) for this weekend.
If you already own the games on Steam (and they're installed), just let the patch download. If you bought them elsewhere, simply register the CD keys with Steam. Steam community users are reporting (opens in new tab) that this will grant you a free upgrade to the GOTY editions, which is nice.
You might want to hold off if you have a game in progress, however, as you'll be unable to retrieve your GFWL-infected save games.
The Steamworks versions of both games now feature achievements, cloud saving, Big Picture mode, trading cards and proper controller support. (Ta, Joystiq (opens in new tab) )
