From the review:
"Resistance: Retribution is the latest portable conversion in Sony's roster. Retribution helps to fill in some of the story between Fall of Man and Resistance 2. It was Developed by Bend Studio using an enhanced version of Syphon Filter: Logan's Shadow engine, with various frame rate and visual improvements. The weapons wheel is back which gives you an awesome arsenal at your fingertips. You will need it; from start to finish, Retribution is action-packed."
