|The Concussion Grenade or Conc Grenade is a grenade in the classic Team Fortress games. When the timer goes off, the grenade explodes releasing a blast of energy that pushes anyone in the blast radius away without dealing damage and applying a short-lived disorientation effect. The disorientation effect causes the aim of affected players to sway in a figure-8.
The explosion has inverted force, meaning that the farther out in the blast you are, the more knockback you experience.
It is used by the Scout and Medic.
While intended as a distraction weapon, it has evolved into a tool for faster movement that is almost vital for flag-runners.
