Red Faction: Guerrilla is a third-person shooter game set in an open world environment and played from a third-person perspective. The player takes the role of Alec Mason as he assists the Red Faction to overthrow the oppressive Earth Defense Force (EDF) on Mars. Unlike the previous Red Faction game, which used the Geomod engine, Guerrilla does not allow for the destruction of terrain. However the game's Geomod 2.0 engine allows for buildings, cover, and other structures to be destroyed.
