Borderlands: Mad Moxxi's Underdome Riot

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.

Featuring extensive co-op integration that seamlessly blends the single-player and multiplayer experiences, Borderlands allows players to freely join or leave each other's games at any time for collaborative mayhem or the freedom to choose to play in full single-player mode to experience the world on their own. Borderlands also includes a groundbreaking weapon generation system that offers a near infinite variety of weapons to the player.
