2K has announced a new downloadable content pack for Borderlands, called Claptrap’s New Robot Revolution, due next month.

In it, players will find themselves caught in the midst of a civil war between homicidal Claptrap robots and the Hyperion Corporation’s armadas. Operating as mercenaries for the Hyperion Corporation, players will work to bring down the robot revolution and dispatch their cunning leader the Claptrap Ninja Assassin.

“What gamer doesn’t love a kung-fu-wielding Ninja Assassin Claptrap with nunchuck skills?” said Christoph Hartmann, president of 2K.

Claptrap’s New Robot Revolution will include 20 new loot-filled missions and a variety of new enemies including Hyperion soldiers, “Claptrap-ified” local creatures such as crab-traps, rakk-traps and skagg-traps. Players will also be able to unlock 10 additional skill tree points for a total of 71, and three more backpack slots.

Claptrap’s New Robot Revolution will be available on PC, PlayStation 3 and Xbox 360. It will cost USD $9.99 on PC and PlayStation 3 (about $14 NZD) and 800 Microsoft Points on Xbox 360.
