With just under two months until it hits stores, Activision's forthcoming Deadpool game is picking up steam.  The smarmy Marvel assassin has been due his own game for some time now and soon he'll be shooting and slicing his way through a barrage of bad guys.

Now a couple of other characters are joining the party.  It's been confirmed by developer High Moon Studios that the vile Mister Sinister will be joining the party along with sultry superheroine Psylocke, whose profile has been included below.

"I thought it was pretty clear when I said I wanted a true Deadpool game that it would star Deadpool...in every role!" Deadpool explained in the press release. "My star power shouldn't be limited to the central protagonist. I should be playing the hero, the anti-hero, the villain who eventually changes sides to join forces against the TRUE villain (me), the romantic interest, the quirky best friend, the comic relief, and at least 8 other characters in fat suits! Is that too much to ask?!"

Deadpool hits stores on June 25th for Xbox 360, PlayStation 3 and PC
