The second expansion for Gearbox Software's Borderlands is now accepting contestants and Microsoft Points. Mad Moxxi's Underdome Riot is now available for the Xbox 360 version of the game, giving Borderlands loot hounds new areas in which to grind.
What does one get for the 800 Microsoft Points investment? The all-new Riot Mode challenges, offering new things to loot and a bank in which to store all that loot. It may not sound like much for ten bucks, but the description "like Smash TV in coop FPS" seems to actually have some truth to it, making the DLC potentially priceless.
