2K Games has announced the second downloadable content pack for its hit FPS/RPG hybrid.

Mad Moxxi’s Underdome Riot will introduce three new “Riot Mode” areas, and will add a “bank feature” which players can use to store loot.

Like The Zombie Island of DR Ned, Underdome will be released first for Xbox 360 and PS3 with a PC release to follow at a later date.
