Our mother always used to tell us that "destroying something beautiful is always better if you do it with friends." She was, of course, a known anarchist and generally untrustworthy. You can imagine, then, how interested we are to test her words in the destructive Red Faction: Guerrilla MP demo, which is now available to all 360 and PS3 owners (or at least it will be available when the PSN update drops).
If our mom was on the level (it would be quite the anomaly) and you have a blast, you'll be able to pick up the full game on June 2.
