Warner Bros. is still saying sorry for messing up Batman: Arkham Knight this summer.

The publisher has today started gifting four free Batman titles to PC gamers who bought the technically disappointing (and unplayable for some) Batman: Arkham Knight. The offer is open to anyone who bought Arkham Knight from the Steam digital store before Nov. 16, and many people have discovered the free games — Batman: Arkham Asylum, Batman: Arkham City, Batman: Arkham Origins, and Batman: Arkham Origins Blackgate — appearing in their Steam libraries in the past few hours.

Warner Bros. took the unusual step of pulling the PC version of Batman: Arkham City from digital and retail stores earlier this year as it was unplayable on most gaming rigs. It was a big deal, especially considering the importance of the big-name release in Warner Bros.’ publishing schedule.

Batman: Arkham Knight reappeared on Steam at the end of October, but it still posed problems for many players, and Warner Bros. promised full refunds until the end of the year. The publisher is hoping to further salvage its reputation in the PC community with this new giveaway, but not everyone’s happy — some Steam users are saying they haven’t received the free games yet despite being eligible.
