Slowdown

Shoot, son, you all slow as molasses. Click to listen — The Engineer

Slowdown, or slow for short, is a gameplay mechanic that decreases the speed of a player for a set amount of time. This effect can be applied to a player when under attack by certain weapons or as a penalty for using a certain item. In addition, players can naturally slow down their own movement speed by crouching (33%) or by running backwards (10%). (See Classes for specifics on how much a particular class is slowed down.)

The slowdown effect has no falloff distance; players hit from any distance will always be slowed down by at least a small amount.

Weapon effect

Weapon	Slowdown notes
Sandman	The Sandman's secondary fire launches a baseball that can stun the target for several seconds. The stunned target will be slowed down and cannot use any weapon for the duration of the effect. If the baseball is launched at the maximum ranged distance, the victim will be completely immobile and not be able to move at all for the duration of the effect.
Natascha	On Hit: 100% chance to slow target. Every bullet that hits the target will slow them to approximately 113 Hammer units per second. Differences in class or normal running speed does not change this figure. The slowdown effect is reduced the further away the target's distance. It is currently unknown as to how much speed is reduced over what distance. Disguised Spies will not be affected by slowdown from this weapon.

Environmental slowdowns

Cause

Slowdown notes

Scared

On the maps Harvest Event, and Eyeaduct, occasionally, a ghost or ghosts will wander around certain areas of the map. If any players are near, or come into contact with the ghost, they will be frightened and have their movement speed reduced in addition to being unable to fire any weapons, much like when stunned. The Horseless Headless Horsemann in Mann Manor can scream and inflict a similar effect on all players nearby.
