The drone is the zerg worker unit in StarCraft II.

Game UnitEdit

Drones are rallied separately from other units with the "G" key, which can be combined with automine. Unlike their predecessors, they no longer have a ranged attack.


Unlike most other zerg ground units, drones do not gain a speed boost on creep.

Exceptions include:

Some units can unburrow via autocast, causing them to emerge and attack when an enemy moves into range.

Co-op MissionsEdit

The original drone render in StarCraft II

In earlier builds of StarCraft II, drones were not required to build defensive structures, such a role having been taken over by the queen.[2] Drones have regained their ability to create defensive structures.[3][4]
