The object of the game is to break the most expensive furniture you can find! You start out at a party in your friend's apartment. You have a knife (for couch-slashing) and a rock (for breaking glass). You have to somehow get everyone out of the apartment and let loose! After beating that you move onto your neighbor's house, your house, the mayor's house, the governor's house, the town hall, the city courthouse, etc. Some of the final levels are the White House, and Martha Stewart's house!
Moving through the game, you find better, and more effective equipment, but some cost money. You find money in couch cushions and in jars and desks that you break. Some equipment upgrades are: a jack hammer, an axe, a flamethrower, and much more!
There is also a multiplayer mode, where you buy furniture and try to wreck your opponents' at the same time.
