A video game based on The Boondock Saints film franchise has yet to be officially announced, but already some details are leaking out -- after all, the MacManus brothers aren't exactly known for playing by the rules, unless it comes to truth, equality or shooting mobsters through the back of the skull. Critical Mass Interactive is developing the unannounced title, which is going to be a "full-on co-op shooter" for PC, Xbox 360 and maybe the PS3, CEO Matt Scibilia told G4.

Scibilia would like to release the game as a full retail product, but it may end up in episodic, downloadable form, he said. "We don't want to do a crap-ass franchise game," Scibilia said. "We're staying true to the content. We're looking to expand the story, not just retell the franchise.

"The Boondock Saints characters are so strong -- the banter, the relationships between Rocco and the brothers, the Catholicism, that will all be featured in the game."

Critical Mass Interactive will join members of the original Boondock Saints cast at SXSW's ScreenBurn Arcade series on Sunday, March 11 in Austin, Texas to talk details. Critical Mass also plans to show off the game in secret sessions at PAX East in April, and will reveal it for a wider audience at E3. Until then, watch the above trailer -- please watch it. You don't know how long it takes to find a reel of this film without any f-bombs.
