A new full-on, co-op shooter that will likely be episodic and based on the Boondock Saints films is apparently in the works. Sources say that developer Critical Mass Interactive is developing the title that will be coming to the PC and Xbox 360. (A PlayStation 3 release is possible at a later date.)

The title has not yet been officially announced, but we hear that Critical Mass Interactive will be joined by members of the Boondock Saints cast at the SXSW ScreenBurn Arcade series on Sunday, March 11th in Austin, Texas where the first details will come to light. Secret sessions are planned for PAX, as well, in April.

Then a much more in-depth reveal is planned for E3, where the company is planning to show off the game to a much wider audience. Sources tell us that the game will be “true to the content” and it will expand on the story, rather than simply re-telling it.
