You can become the night for 66% off with these weekend sales. Batman Arkham Asylum Game of the Year Edition is marked down to $13.60 at SteamPowered.com. This is the GOTY version with several extra challenge missions. It’s a great deal on a spectacular game, and the PC version has spawned a small modding community who make alternate outfits for your caped crusader to wear as he battles evil.

Keep this up GFWL and we’ll forgive you for hiding our game save files, and Fallout DLC.
