Are you still playing Bulletstorm?! Really? Wow, okay, well hey! There's new downloadable content for both the Xbox 360 and PlayStation 3 versions of the game today! For 800MS Points/$9.99, you'll get three new Anarchy maps (Sewers of Stygia, Hotel Elysium and Villa) and two new Echo mode maps (Crash Site and Guns of Stygia.)
The new content will also include Flamingo and Pulp leash variants, which I'm guessing is just alt colors for your leash weapon. Neato?
PC owners of Bulletstorm will be getting the new maps, just not right now. The DLC will be available "soon" according to EA.
