THQ have announced a release date for Red Faction: Armageddon on the Xbox 360, PlayStation 3 and PC. Its currently slated to release the week of E3 2011 - with a June 7th release date in North America and a June 10th release date internationally.
Red Faction: Armageddon has one planned co-op mode called Infestation where four players take on waves of enemies online. Its your traditional survival/horde style mode - but with a Red Faction twist. Players will be able to manipulate the environment using various weapons that destroy as well as put the landscape back together. The latter is key in creating defensive areas to survive in.
THQ also announced that a playable demo of Red Faction: Armageddon will be available on the Xbox 360 on May 3rd. No word on any other platforms for the demo.
