When Sean reviewed the last Borderlands DLC, The Zombie Island of Dr. Ned, he pointed to a distinct lack of new loot and character progression as its main faults. Indeed, in a game heavily based around getting exciting new loot and progressing your character, these are some pretty major drawbacks.

Well, Gearbox appears to have learned at least partially from these glaring omissions. The company’s next expansion was officially revealed today as Mad Moxxi’s Underdome Riot, a new experience based around what the company calls “three new Riot Mode arenas where players will endure an onslaught of Pandora’s baddest enemies.” This expansion promises to add more than new enemy types, including a storage system for loot emergencies and, most importantly, the ability to gain two new skill points to apply to your likely maxed-out characters.

Read on to find out more.

So, will these two skill points be enough to provide a richer experience than the last expansion? Xbox 360 players will get the chance to find out on December 29th for 800 MS Points, and PlayStation 3 players will be just behind on January 7th at $9.99.  Check out the company’s full press release below.

New York, NY – December 10, 2009 – 2K Games announced today that the second piece of downloadable content for Borderlands™, Mad Moxxi’s Underdome Riot, will be available on December 29, 2009 from the Xbox LIVE® Marketplace for the Xbox 360® video game and entertainment system from Microsoft for 800 Microsoft Points and on January 7, 2010 from the PlayStation®Network for $9.99. The downloadable content will also be available on Windows PC. This explosive piece of action-driven content is in development at Gearbox Software and provides players with more methods of destruction as they tear through the denizens of Pandora.

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.

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. Borderlands combines these fan favorite features with addictive non-stop action to form a breakthrough experience that challenges the conventions of modern shooters and RPGs.

Borderlands™, rated M for Mature by the ESRB, is developed by Gearbox Software and is currently available for the PlayStation® 3 computer entertainment system, the Xbox 360® video game and entertainment system from Microsoft and Windows PC. The Zombie Island of Dr. Ned, the first piece of downloadable content for Borderlands, is currently available for all platforms.
