Slowdown

Shoot, son, y'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' movement speed is naturally slowed to 90% of their base speed while running backwards and to 33% of base speed while crouching (see Classes for specifics on how much each class is slowed).

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

List of slowdown-inflicting weapons
Scout	Melee		The Sandman's secondary fire launches a baseball that can slowdown the target for several seconds. The target is slowed down for the duration of the effect based on distance.
		Sandman
Heavy	Primary		On Hit: 100% chance to slow target. Every bullet that hits the target slows 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 based upon the target's distance, gradually becoming less effective from 512 to 1536 Hammer units away, where it no longer slows the target at all. Disguised Spies and enemies that are being healed by a continuous source of healing are not affected by slowdown from this weapon.
		Natascha
Note		Includes Festive, Botkiller, and Australium variants.

Environmental slowdowns

List of environmental slowdowns
Ghost Horseless Headless Horsemann		On certain Halloween maps, one or more ghosts occasionally haunt certain areas of the map. Any players who get near or come into contact with these ghosts are frightened and have their movement speed reduced in addition to being unable to fire any weapons, much like when stunned. The Horseless Headless Horsemann can scream and inflict a similar effect on all players nearby. On certain Halloween maps, players change to ghosts when they die in the end-round Underworld. Ghost players do not scare other players as non-player ghosts do.
