If you’re starting to get itchy feet as you glide around the crazy gunfest that is Gotham City Impostors, then we’ve got some good news. This week you’ll be getting a brand new map, totally free, letting you cause even more chaos in the all new Arkham Asylum map. While it’s not the same surroundings that you’ll find in the game bearing the same name it looks from the trailer like there’s some great spots for a good battle. We said in our review that this game would hinge on the support from the developers, and they haven’t disappointed so far. Check out the trailer, and go and grab the freebie.
