Stun Grenade

Crossfire already has grenades, flash, and smoke. But what about stun grenades?

Toss one into a room where you suspect a camper, storm in and spray. Players will be dazed and unable to move for a few seconds.
This would also be really cool for mutation mode. Say you're out of ammo and the mutants are gaining on you. Toss a stun grenade and boom they're all stunned and you can make your getaway...

Stun grenades would add a whole new element to this game.
I doubt it would be hard to add...
