A newly posted listing from the Australian Classification Board confirms an MA-15+ rating for a previously unannounced video game adaptation of The Expendables 2 (via Polygon). The Ubisoft-published title is flagged for its "strong violence" and apparently includes some sort of online component, since the listing notes that "gaming experience may change online."
There's no mention of release date, platform(s), or anything else, though the game will presumably hit stores in reasonably close proximity to the summer action flick's August 17, 2012 release. I'm also going to go out on a limb in speculating that this game is probably going to include guns. Lots and lots of guns. And if you have zero idea of why I might reach that conclusion, you should probably go check out The Expendables 2 trailer.
