Borderlands was a little underling when it was released amidst a holiday ruled by Call of Duty: Modern Warfare 2. The game has sense gone on to do very well and they are now releasing their 4th DLC pack for the game Claptrap’s New Robot Revolution. A rebel claptrap known as Ninja Assassin has kung-fu skills and is manning a revolution against the inhabitants of Pandora. The pack will have you facing all kinds of Clap-trapified enemies such as Skag-Traps and Crab-Traps. The DLC is set to release on all Xbox 360, PS3, and the PC for $10 some time in September.
