From the press release:
The Deckers... elite cybercriminals... hackers... unrelenting online gamers. Their next target: the Third Street Saints. Upon arriving in Steelport, the Saints find their bank accounts wiped out by a Deckers cyber-attack. For the Saints, there's only one thing left to do: hack into the Deckers user-net, engage in their own brand of cyberbullying, and shut down the Deckers' network... permanently. But in this world, Deckers mastermind Matt Miller is a virtual god, capable of altering physics, setting firewalls, and unleashing his own deadly, maxed-out avatar. Are you ready to f*** s*** up in virtual reality?
Saints Row: The Third is a badass, open-world, irreverent-as-hell, high-powered action game in which you can call down a military strike on your fellow gang-bangers, take to the sky in a state-of-the-art fighter plane and generally wreak havoc any way you like.
It's headed to store shelves in November, for Xbox 360, PlayStation 3, and PC.
