Unless you have a core group of three other friends and all of you have maxed out level 50 characters, I wouldn't recommend Borderlands: Mad Moxxi's Underdome Riot to you. It isn't balanced properly and, since there is no normal XP awards or loot drops, you won't find your character improving as your struggle through the endless waves. It actually encourages you to leave the Underdome to go grind your character. All of the style and great music in the world can't save this add-on from the fact that it had the soul of Borderlands ripped out.

About this Game

Mad Moxxi's Underdome Riot is an intense single-player or cooperative experience for Borderlands that expands the mayhem by adding three new Riot Mode arenas where 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.
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.
