Plot

Mad Moxxi is a thrill-seeking woman in search of a new husband. Having gone through three husbands already, her search has led to her becoming the Ring Master/Hostess and Commentator of the Underdome. She equates the excitement and the competition of the Underdome to matrimony and plans to stay only as long as the thrill lasts. Gameplay includes three new Riot Mode arenas where players will fight AI-controlled enemies (PvE) in single player or multiplayer [4]. The add-on starts with the mission titled "Prove Yourself" in which players complete all three arenas. This is the only DLC that doesn't contain a full plot with side missions and multiple plot missions. After successful completion of "Prove Yourself", though, the player is allowed unlimited replays of all content, including the three arenas with 20 5-wave-rounds instead of 5.

Mechanics

Main article: Underdome gameplay mechanics

The DLC can be accessed in-game by using the Fast Travel system and heading for the starting location of The Underdome. The gameplay consists of rounds and waves. Each round consists of five waves ending with a Boss wave. Every round brings an increased difficulty level. As the round number increases, the number of gameplay-altering rules increases, adding variables such as different gravity levels and modified enemy regeneration, accuracy, damage, etc. If a character is incapacitated and fails to achieve a second wind they will respawn in the Penalty Box on top of Moxxi's tower and the round will be reset. If the player is downed in a multiplayer game, they will respawn in the Penalty Box (from which they can still play an active role by sniping enemies) for the remainder of the wave.

No experience is gained from kills inside the Underdome and consequently weapon proficiencies are not affected, although it is still possible to complete challenges for experience.

Trivia

The title "Mad Moxxi's Underdome Riot" is a reference to Mad Max: Beyond Thunderdome .

. In the trailer for the DLC, when Moxxi's first husband is shown, the Konami Code runs across the screen, shooting him.

The tournament audience sometimes gives a cheer of "Heyooo!" a greeting otherwise used by Steve. Steve is featured in many Borderlands promotional works, including the 'Borderlands Claptrap Web Series'. Killing a humanoid opponent (such as a bandit or psycho) with a critical hit will usually prompt the cheer. Yet another reference to Steve is in the intro clip that plays the first time you fast travel to the Underdome, when Moxxi describes her former husbands. For number two, you see the shadow of a Bandit Raider and hear "Heyooo!" shortly after he appears.

After players unlock the greater challenges, dead bandits can be seen buried with flowers planted on their exposed heads.

Mordecai is the only character who is canonically stated to have won The Underdome Challenge as revealed in the Borderlands 2 side mission Rakkaholics Anonymous.
