The Borderlands Double Game Add-on Pack contains the first two add-on content packs released for the popular first-person shooter Borderlands, now consolidated on a single disc.

Loaded with tons of release specific missions, over-the-top zombie and riot arena combat that includes single and multiplayer action and exclusive rewards, the combination of The Zombie Island of Dr. Ned and Mad Moxxi's Underdome Riot serves as the perfect complement to the original game.

Originally, released as a digital content download, Borderlands: The Zombie Island of Dr.Ned centers around the town and surrounding areas of Jacob’s Cove, unofficially named Zombie Island. Here players are tasked with the completion of 20 exclusive Borderlands missions, involving the zombie infestation of the island, as well as various optional side quests.

Borderlands: Mad Moxxi’s Underdome Riot is the second add-on pack for Borderlands. Designed with a Mad Mad Thunderdome ethic and feel, action occurs within a series of spaces known as riot arenas where the changing rules, commentary are mood are provided entirely at the whim of the over-the-top and seductive ringmistress, Moxxi.
