The latest downloadable content (DLC) for Borderlands, Mad Moxxi’s Underdome Riot, may well have already released on Xbox LIVE for 800 MS Points, but it’s yet to arrive on the PS3 or PC, so while those of us without an Xbox 360 wait for the DLC to arrive (on January 7th for PS3 and later this year on PC), we can enjoy some fantastically stylish videos featuring the new content and backstory that will be added to Borderlands.

Mad Moxxi’s Underdome Riot contains a new cooperative arena mode featuring three locations (namely Hellburbia, Angelic Ruins and The Gully) where you’ll be challenged to take on waves upon waves of enemies in an effort to emerge from the arenas alive and in tact.

You can watch the opening cinematic to Mad Moxxi’s Underdome Riot, as well as a gameplay video from the content, below:
