In each game for the series, an engine called Geo-Mod, short for “Geometry Modification” technology, is present in some form. Players go around completing missions for the Red Faction and perform guerrilla actions to liberate various sectors of Mars from the control of the Earth Defense Force. Purchasable weapons include an Arc Rifle, Grinder, Rocket Launcher, Proximity Mines and a Nano Rifle. These weapons are mainly purchased using salvage, the main currency of the game, with the exception of the remote charges and assault rifle, both of which are given to the player by default at the start of the game. Players are usually equipped with four weapons, the primary weapon is a Sledgehammer with three more weapons of the player’s choice. In the games, all environments are fully destructible which means that every single building in the game can be destroyed. Armageddon is a more linear experience, largely moving through corridors and caverns from objective to objective. Guerrilla takes place in an Open world environment on the planet of Mars allowing players to free roam across the environment. Rather than the traditional first person shooter style of the first two games, both Guerrilla and Armageddon utilize a third person style of gameplay. While the first two games did not re-invent the first person shooter, their Geo-mod Engine and rebellious story made both games a new step for the genre. The games include vehicles, pistols, rifles, explosives, and other traditional shooter weapons and features. The first two games were traditional first person shooters with unique environmental destruction features that were praised in both games.

This was enhanced in Red Faction: Guerrilla when it was applied to every building in the game making the game’s entire environment destructible.

Both styles share a common element, the series’ unique environmental destruction features. The series has had three unique styles of gameplay, the first is a traditional first-person shooter element which was used by the first two games in the series, while the second is a third person style of open world gameplay which was used in Red Faction: Guerrilla and a third person style of corridor shooter used in Red Faction: Armageddon.
