A stunned Pyro
Too slow!
The Scout

Being stunned is the state of being incapacitated. While stunned, a player cannot attack and is either locked in place completely or is severely slowed.


The Engineer's Arm Blender, the Medic's Uberslice, and the initial stab of the Sniper's Arrow Stab fully stun a player if they connect. These attacks can stun an ÜberCharged opponent. ÜberCharged enemies are often distracted or keeping their aim at a Sentry Gun, long enough to stab them with the taunt. Even without damage, it wastes precious seconds of ÜberCharge.

The Ghosts on Halloween maps can scare players, as well as the Horseless Headless Horsemann's taunt on Mann Manor. This counts towards achievements as a stun.

In Mann vs. Machine, Sappers can be placed on robots to disable them; but, unlike the "scared" effect, this is an ordinary full stun, and can even trigger Sandman voice lines if the Spy placing the Sapper is disguised as a Scout. Giant robots are immune to being stunned, but still receive slowdown from Sappers and the Sandman for the duration of the effect. All regular-sized robots on the map Mannhattan are automatically stunned for approximately 20 seconds whenever a point is captured. Additionally, an upgraded Thermal Thruster can stun robots within a certain radius upon landing.

In Mannpower, the Supernova ability grants the player the capability to fully stun nearby enemies upon activating the attack, which requires a full powerup meter to perform.


When partially stunned, a player's speed is decreased by 50%. The below table lists the exact values in Hammer units.

  • Consecutive Airblasts will no longer prevent enemies from air-strafing until they touch the ground.

October 20, 2017 Patch (Jungle Inferno Update)

  • Changed attribute on the Sandman:
    • Long-range ball impacts no longer remove the victim's ability to fire their weapon (but the victim is still slowed).
  • Changed on the Airblast:
    • Airblast now causes target player to have reduced footing and air control for a short period.
      • No longer a flat stun.


  • Being stunned while taunting allows a player to move at the reduced stun speed before the taunt's completion.
  • It is possible to taunt while stunned.
  • Being stunned while contesting a control point stops the player from contesting that point. This does not apply to Ghost scares.
  • It is possible to perform melee attacks while stunned with the Disciplinary Action.
