Speed is a property of units and attacks. Faster units have the freedom to flee from or force an engagement with slower units. Movement Speed is measured in game distance units per second (these are the same distance units used to measure Range).

Superscript Key [ edit ]

By default, Zerg units are off creep and unburrowed, and all units have no speed upgrades. Units that benefit from creep and/or speed upgrades are listed more than once.

S : Unit after passive speed upgrade

: Unit after passive speed upgrade B : Zerg unit Burrowed

: Zerg unit Burrowed C : Zerg unit on Creep

: Zerg unit on Creep A: Unit using activated speed ability

Movement Speeds by Speed [ edit ]

Units here are divided into general categories of mostly similar speeds, although Very Slow and Very Fast also contain the outlying units.

Movement Speeds by Unit [ edit ]

Abilities that affect Speed [ edit ]

Acceleration [ edit ]

Units also have Acceleration, the rate by which speed increases until the maximum. Acceleration is partially responsible for how agile and easy to micro units are. For example, Vikings, Ravens and Banshees have the same movement speed, but different accelerations. Air Units and Workers have defined accelerations. Ground units other than workers, as well as Interceptors, have effectively instantaneous acceleration (1000). Gravitic Boosters, Gravitic Drive and Ignite Afterburners also increase acceleration.
