So if you head on over to the Humble Store this weekend, you might notice they're having a Batman: Arkham sale, including the opportunity to pre-order Arkham Knight before it comes out next week.
The realy cool thing, though, is that you can get Arkham Origins, Arkham, City, and Arkham Asylum for just $4.99 apiece. Head on over there and check it out.
oh my that nananananana reference XD
