A weapon common to <FILL IN YOUR GAME HERE> Fortress mods. Similar to their real-life counterparts, conc grenades are non-lethal, designed to disorient the target by distorting its view. Typically carried by light-combat units (Medics, Engineers, etc).

Conc grenades, however, are usually hated by newbies for the infamous Concussion Jump maneuver. As conc grenades are non-lethal but still have a blast to them, players who routinely use units with concs throw them on the ground and time their jumps to coincide with the grenade blast, sending them skyward with no damage, besides fall damage. Much like Rocket Jumping, but with far less damage and a dizzying effect instead of pain.

This node comes from a noder who does not devote his life to Fortress mods. Sorry.
