Gearbox and 2K have revealed that the next Borderlands DLC will be Mad Moxxi’s Underdome Riot.The new DLC is scheduled for a 29 December release on the 360 via the Xbox LIVE Marketplace for 800 Microsoft Points, and on 7 January 2010 for the PS3 via the PlayStation Network priced $9.99. The content will also be available on PC at what we can only assume will be some time after the PS3 release. The PR blurb reads:Mad Moxxi’s Underdome Riot is an intense single-player or cooperative experience that expands the mayhem by adding three new Riot Mode arenaswhere players will endure an onslaught of Pandora’s baddest enemies. Working together, players will fend off the masses as they fight for fame, honor, and more importantly, loot. Mad Moxxi’s Underdome Riot also adds a new bank feature, which allows players extra storage capacity for when they encounter one of the more than 16 million weapons that Borderlands has to offer; and the ability to acquire two additional skill points as quest rewards, making their characters even more powerful than before.
