Sandbox action game Saints Row 2 has just received its second chunk of downloadable content. The Corporate Warfare DLC is now on Xbox Live and should hit PSN later today.

Corporate Warfare continues the SR2 storyline and brings you in direct conflict with the evil Ultor Corporation. It seems their new Head of Security is running a black market nuclear weapons operation and it's up to you and your gang to stop them. The downloadable content also adds new vehicles (aircraft, exotic cars, and superbikes), more customization options, and maps for Strong Arm and Gangsta Brawl multiplayer modes.

Warfare will set you back 560 Microsoft Points ($7). The releae comes about a month and a half after the debut of the first DLC, Ultor Exposed.
