Borderlands combines the best in first-person action with player customization and vehicular combat to deliver an exciting Role-Playing Shooter experience. The game features a groundbreaking content generation system allowing for near-endless variety in weapons and item drops. Borderlands allows for multiple players to share the same game experience simultaneously online in co-op gameplay. Players can freely join or leave each other's games at anytime, or choose to play in the full single-player mode. These features, along with a rich and deep fiction that touches upon the mysteries buried beneath the surface of a danger-filled planet, combine to form a breakthrough experience that challenges the conventions of modern shooters.

Mad Moxxi’s Underdome Riot is an intense single-player or cooperative experience 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.
