PAX East attendees will get an early look at Red Faction: Armageddon's Ruin mode. Similar in theme to Guerrilla's Wrecking mode, winning is all about chaos on a mass scale. From the press release:

"Introducing Ruin, Red Faction: Armageddon’s mode dedicated to pure destructive mayhem. Choose your weapons, enter the arena, and unleash hell. Chain together explosive combinations for bonus points, and compete with your friends’ high scores on the online leader boards in Challenge Mode. Or engage in untimed Free Play rounds in which you explore the surface and seek out its most destructive secrets."

If you stop by THQ's booth, make sure to sign up for the Ruin competition for your shot at a few undisclosed prizes.
