Resistance: Retribution takes place a few months after the events in the first game, Resistance: Fall of Man. We take on the role as a insufferable douchebag named James Grayson that are making exceptionally bad decisions based on the need to revenge his brothers' death and that he feels let down by the army and his country. When awaiting his execution (yeah, he eventually is sentenced to death) he gets a visit from this french woman named Raine Bouchard who gives him an opportunity to extract said revenge after all. And I guess this also is the seed to what can evolve into the road to redemption, if you will.

Making a third person shooter work well on the PSP isn't the easiest thing in the world concidering that there's only the one thumbstick but Bend Studios (yes, the guys who did Bubsy 3D, the two Uncharted games for Vita and the upcoming Days Gone) came as close as I think it'll get. The thumbstick is used to moving around and the face buttons are used to aim. Specific in game actions are triggered by the d-pad and the shooting is done with the shoulder buttons. Granted, using the face buttons as a way to aim is clonky at best, but they have also included a very generous aim assist that makes up for the lack of precision.
