Manhunt 2 Glitch - No Revolver/Shotgun Executions!

Manhunt 2 - ps2 - Game Glitch #1 - No Revolver/Shotgun Executions! When ever I try to do an execution with a revolver or shotgun, the game cuts to the static/spinning square thing, and freezes on it. I have to reset my ps2 to get the game going again! I need to know if it's just my disc, or if this is a common glitch! If it's my disc, I'll go ahead and take it back! Thanks to those who help me out! UPDATE! - took the game back and exchanged it! New copy is workin' fine! Please Visit: http://www.bonersgames.com and support my gaming addiction! (DO IT!)
