Bend Studio has created an all new story, levels, weapons and enemies, as well as a proprietary targeting system that takes full advantage of the PSP control system. Their third generation PSP game engine pushes the system to its limit, allowing more detailed characters, special effects, and terrain that captures the look and feel of the Resistance universe on the portable system.

Set in the weeks after Resistance: Fall of Man, Resistance: Retribution follows the story of former British Marine James Grayson. After a personal tragedy ? he is forced to kill his own brother inside a Chimeran conversion center ? Grayson goes on a vendetta to destroy every conversion center he can find. Eventually Grayson learns that his efforts have been futile... in Western Europe the Chimera have evolved a new method of converting humans to aliens. The European resistance ? the Maquis ? enlist Graysons help, and he joins Cartwright and Parker in Operation Overstrike. The war to retake the European continent has begun.
