On August 11, 2010, 2K confirmed the title of the content, "Claptrap's New Robot Revolution", and its main premise. The DLC has 21 missions (split between 9 main missions and 12 side quests), 2 new skill points, and six additional backpack slots. The game focuses around a rogue army of brainwashed Claptraps (led by CL4P-TP, Interplanetary Ninja Assassin, the same Claptrap that is seen getting struck by lightning just after the end credits of the main game) who plan to destroy humanity for their mistreatment, along with an army of familiar enemies transformed into Claptrap styles (i.e., Crab-Traps, Rakk-Traps, and Skag-Traps). A wide variety of old cast members return alongside new faces. New fast-travel destinations were also expected, a first for "Borderlands" DLC, but ultimately they were not included. On September 5, 2010, Pitchford announced at the Penny Arcade Expo that the release date was scheduled to be September 28, 2010. Pitchford also announced a free patch to increase the level cap by 8 for all players (to a maximum of Level 69, or 58 for those without "Knoxx's Armory"), regardless of whether the expansion had been purchased.
