Red Faction Guerrilla is a third-person shooter video game developed by Volition and published by THQ. It was released for PlayStation 3 and Xbox 360 in June 2009 and for Microsoft Windows in September 2009. The game is the third installment in the Red Faction series. A remastered version, dubbed Re-Mars-tered, with improved graphics was released on July 3, 2018, for Microsoft Windows, PlayStation 4 and Xbox One. It will include graphical upgrades, and support 4K resolutions from the console versions. The remastered version will be provided free to those users on Steam that own the original game.
Set in an open world environment, the player takes the role of Alec Mason as he assists the Red Faction to overthrow the oppressive Earth Defense Force (EDF) on Mars. Developer Volition changed the camera perspective to help the player see and appreciate the surroundings as they are destroyed. 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. This allows a degree of creativity in approaching a given objective, such as breaking or crashing through structures, or leveling multi-story buildings and large bridges or catwalks to thwart the enemy.
In many cases, destroying buildings will leave behind salvage, the game's form of currency, which can be used along with salvage rewarded by completing missions to unlock and upgrade weaponry and technology at safehouses. During the campaign, the player is always equipped with a sledgehammer-like weapon, along with three slots for other weapons and explosives, selected out of a choice of almost twenty items. The player also has the opportunity to control armed vehicles ranging from retrofitted civilian vehicles up to tanks and large walkers for more destructive options against the EDF.
