Rather than focusing on Nathan Hale, the protagonist of Resistance: Fall of Man and Resistance 2, Resistance: Retribution centers on James Grayson, a former British Marine whose story bridges the two-year gap between the two PS3 titles. After Grayson is forced to kill his own infected brother, he makes it his personal mission to destroy every remaining Chimeran conversion center. Unfortunately, he soon learns the alien-like Chimera have developed a new method of converting humans, but Grayson vows to continue his crusade by joining the European resistance.Unlike its first-person predecessors, Retribution takes on a third-person perspective, more akin to developer Sony Bend's Syphon Filter games, and makes use of a unique targeting system designed specifically for the PSP. The 20-mission single-player campaign has players following the Chimera, and other nasty enemies such as the mysterious Cloven, through the Netherlands, Luxembourg, France, Poland, and Germany. Up to eight players can join in for local or worldwide battles in five multiplayer modes, including: "Team Deathmatch," "Capture the Flag," "Containment," and "Assimilation." Gamers who own a PS3, Resistance 2, and a second- or third-generation PSP, have the ability to use a Dual Shock 3 controller when playing Retribution, and players who connect the two games can unlock a new "Infected" mode that changes Grayson's appearance, gives him regenerative health, lets him breathe underwater, and alters the way others interact with him
