Say what you will about Saints Row 2, you can't say Volition aren't supporting the game post-release. They've just announced a second DLC pack for the game, called "Corporate Warfare".
Due on May 28, it'll introduce a new set of missions where you have to take on the Ultor Corporation, along with other stuff like new weapons, multiplayer maps and vehicles.
360 owners will be paying 560 MS Points, PS3 owners will be paying 7 Real World Dollars.
