Red Faction Underground now offers two more "tools of destruction" trailers from Red Faction: Guerrilla, Volition's upcoming destructible shooter sequel. Here's the description of the new clips: "Mack is back with two more videos showcasing the key weaponry you’ll be using in Red Faction Guerrilla come June. First up, a powerful showcase of the Arc Welder and the Grinder. Many of our MP Beta testers were able to get their hands on the Grinder back during our initial testing, but we’ve got a special surprise tucked within the video below that will change the way you use this weapon in the final game."
