That gun looks like a P90 futurized... Thus it's cool.
Oh, not the box art, it's still dimwhitted... The gun is cool though, not stealthy, mind you... Turn off the cold cathode light and you've got a stealthy cool gun. The barrel looks like it's a projectile weapon, so I don't understand the lights... Are they the conduit? Is the sphere the conduit? If so, is it fair to call it a conduit? Maybe that friendly looking resident of Washington D.C. to the guy's side could help, though he looks a bit frightened by the douche's audacity to hold a gun in public. I mean, look at the damage this guy has done with his conduit and gun! Oh, the box art explains it all so well to me now!
