Borderlands expands with Mad Moxxi's Underdome Riot

Yesterday, Gearbox Software completed the first round of downloadable content for its postapocalyptic role-playing shooter Borderlands, launching the PC version of The Zombie Island of Dr. Ned. Today, 2K Games and Gearbox returned with more news concerning Borderlands DLC, announcing that the second add-on pack, titled Mad Moxxi’s Underdome Riot, will hit Xbox Live on December 29, with the PlayStation Network edition following on January 7.

Whereas The Zombie Island of Dr. Ned expanded Borderlands' storyline by adding in an abundance of zombies, Mad Moxxi’s Underdome Riot adds in a new survival gameplay mode. Available for both single-player and cooperative action, Riot Mode features three arenas in which gamers face off against increasingly frenetic waves of enemies.

"This is an entirely new game mode," said Gearbox CEO Randy Pitchford in a statement. "Think ODST's 'Firefight' or Gears of War's 'Horde Mode' [with] cash, prizes and competition. It's like Smash TV in coop FPS, but in the Borderlands."

The add-on pack also introduces a new bank mechanic for storing found objects, as well as the opportunity to acquire two new skill points as quest rewards. As with the first add-on pack, Mad Moxxi’s Underdome Riot will cost $10 (MSP800). Also, as with the first, a PC edition of the expansion is planned, though 2K Games offered no release window for it.
