Stun grenades, sometimes called wizz-bangs, and flash-bangs, work on flash and shock basis to distract opponents. When eg exiting labs where enemies are ready to shoot as soon as MO rounds a corner, having one to lob into a room could be modded for eg 3 second delay, so MO could pop out and shoot or move to better cover. Perhaps a new grenade mod?
