Batman: Arkham City not GFWL
Holy download Batman!
Batman: Arkham City is not a Games for Windows Live title, according to online shop Green Man Gaming.
A Tweet published this morning read: "We've just received notice from Warner's [sic] that Batman is Games for Windows but NOT a Games for Windows 'Live' title!"
In June box art for the game showed the GFWL logo, suggesting Rocksteady's game would use Microsoft's PC gaming frontend. Batman: Arkham Asylum used GFWL.
Eurogamer has followed up with Warner Bros.
