Red Faction Guerrilla

“Lured by the rich veins of Martian ore, miner Alec Mason arrives on Mars hungry for a new life. But the promise of a brighter future for Mason quickly fades. The Earth Defense Force, once protectors of Martian colonists, have adopted heavy-handed checkpoints and omnipresent armed patrols.

“As violence escalates, an underground resistance known as the Red Faction is swiftly gathering strength to combat the EDF. Mason’s quest for a new life has become a battle for survival, and the fate of the planet now rests with him and the Red Faction.”
