Not sure by your question if you need a description of the game or not.... but here is the XBox 360 description of the game.....
The Third Street Saints have gone from most wanted to officially licensed. The marauders hit the big-time, and get their names and faces on bobbleheads, sports drinks, and more. A global criminal organization known as The Syndicate takes notice and demands tribute. Bad idea. The Saints devise a payment plan that includes mayhem, vengeance, and the kind of anarchy they've turned into an art form. Let it all hang out as you explore an open-world playground where there's no such thing as too over-the-top. If what you're doing isn't the craziest thing you've done in a game, it's probably because you still haven't gotten over what you just did a couple moments before.
