click to enlarge The latest item of DLC coming to Borderlands adds new, combat-focused content to the game ... while simultaneously removing any artifice with which Gearbox was obscuring the universe's cinematic inspiration. Mad Moxxi's Underdome Riot (get it?) adds three new Riot Mode arenas for single-player or co-op, along with a new bank feature for storing weapons. That's right, a bank. For weapons. That pretty much guarantees you'll pony up the 800 Microsoft Points when this comes out December 29 on Xbox, or the 10 bucks for the PS3 version on January 7. No date or price has been announced for PC. Full press release after the break.
