Originally released in 2009 and published by THQ, Red Faction: Guerrilla distinguished itself from other open-world games with extraterrestrial combat, myriad vehicles, destructible - and, later, vaporizable - environments and mechs. Red Faction: Guerrilla Steam Edition removes its Games for Windows Live innards and offers upgrades like DirectX 11 compatibility, Steam Trading Cards, Steam achievements and leaderboards. Publisher Nordic Games released the game after a month of beta testing. Red Faction: Guerrilla, developer Volition's Martian open-world shooter, arrived on Steam today with an otherworldly discount.
