Resistance: Retribution is a third-person shooter developed by SCE Bend Studio and released in 2009 for the PlayStation Portable. Set in the weeks immediately following Resistance: Fall of Man, the game centers on James Grayson, a former British Marine who is forced to kill his infected brother inside a Chimeran conversion center. Consumed by grief and rage, Grayson embarks on a personal campaign to destroy every conversion center he can locate, only to discover that his efforts have had little impact — in Western Europe, the Chimera have developed an entirely new method of converting humans. Recruited by the Maquis, a European resistance organization, Grayson joins operatives Cartwright and Parker in a mission called Operation Overstrike, aimed at reclaiming the European continent from Chimeran control. The game represents a portable entry in the Resistance series with a narrative distinct from the main console storyline.
Set two months after the events of Resistance: Fall of Man, British Royal Marine Lieutenant James Grayson lead his team on a raid in a Chimera conversion center; Grayson stumbles upon a horrible sight: his long-missing brother; Johnny Grayson, who is already infected with the virus and half-converted into a Menial. Forced to follow the protocols regarding infected soldiers, Grayson makes the impossibly painful decision to shoot and kill his brother. As a result, Grayson suffers a nervous breakdown and deserts from his team, and launches his own personal vendetta against the Chimera. Grayson succeeds in destroying approximately 26 conversion centers, but is eventually captured and taken into custody for desertion. A capital offense; Grayson is put on trial to which Stephen Cartwright, now promoted to Major and Grayson's commanding officer, testifies against him. Grayson is found guilty and sentenced to death by firing squad.
