I was watching the discovery show future weapons and saw them use the corner shot weapon and thought it would be great in a video game.

If programmed properly it would really add a new dimension to the game play, in stealth game how cool would it be to shot the bad guy from around a corner and since it has a camera it can be used to check the landscape with out leaving cover. While it whould be awesome for the gamer to use what I really want to see is the enemy AI programmed to use the weapon properly as well, it would add an extra challenge to be fighting enemy that can shot at you while fully behind cover. The old and still fairly reliably lure baddies to the end of hallway and mow them down as they rushing in would no longer work. It appear that one game, Nemesis Strike, will use this weapon but it not due out till march. Hopefully they will make good use of it.
Jam it back in, in the dark.
