Marauders
Marauders are mysterious creatures in Red Faction: Guerrilla that, in some way, relate to the original Red Faction, and live in The Badlands, a hostile environment.
Description
These barbaric anarchists are known as friends to no one; they're just as hostile to EDF troops as they are to the Red Faction freedom fighters. Wielding big, tridentlike melee weapons, these guys don't opt for using cover and tactics; they're all about offense, aggressively rushing you and attacking until you manage to bring them down.
Plot Role
It's unclear how this third faction fits into the overall plot of Red Faction: Guerrilla at this point, though we do know that at some point, Alec Mason will find himself temporarily allied with the group to achieve an objective.
