StarCraft IIEdit

TerransEdit

In StarCraft II, the supply depot has a burrowing ability, allowing it to sink into the ground so that units can pass over it. However, this ability does not prevent it from being seen. Burrowing has led to the deaths of countless terran soldiers. Terrans were able to mimic this lethality with the Perdition turret that retracts automatically, when not in combat.[1]

Lower/Raise Supply Depot

Lowers the structure into the ground so ground units may pass over it. The structure may be raised back to block pathing. Friendly units standing on the structure are pushed the nearest edge when the structure is raised. Enemy units standing on top prevent the structure from being raised.

The structure's attributes, other than blocking movement, are not changed when it is lowered.

Unlocks the perdition turret for production.[2]

This turret fires a deadly wall of flame that is ideal for holding off large waves of enemy units. The turret also conceals itself beneath the ground when out of combat, luring unsuspecting enemies into its field of fire. The zerg's ability to burrow has allowed them to massacre countless terran soldiers in deadly ambushes. The new perdition turret should help even the score.

Spider Mines pursue enemy units that come in range, and detonate for heavy area damage. Buried Spider Mines can only be seen by enemy Detectors.

ZergEdit

Burrow is a zerg ability used to conceal themselves underground. Ground breeds vibrate billions of tiny muscles at a low frequency; this breaks up earth, rock, and vegetation allowing the creature to "swim" through the ground at near running speeds.[2]

When zerg units burrow in StarCraft II, the player controlling them can see part of them "sticking out of the ground", making it easier to identify them. However, they remain invisible to enemy units without detection.

Burrowed units are treated as a different unit type for UI tab selection purposes, unlike some other status effects.

Roaches and infestors can move while burrowed. Moving while burrowed produces a distortion similar to cloaking. Infestors can also spawn infested marines while burrowed. Ultralisks gained the ability to burrow. In the Heart of the Swarm campaign, lurkers and impalers can attack while only burrowed.

Some critters can also burrow, like the lava crab.[3]

Many zerg ground units may burrow, become invisible and may be revealed primarily by detectors, and may not move or attack.

Exceptions include:

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

The ability is not smartcast.

DevelopmentEdit

The following section contains information from a previous version of StarCraft II: Heart of the Swarm which is no longer valid.

During the development of the Heart of the Swarm, several units have gained burrow related abilities. Banelings gained a hive upgrade that allows them to move while burrowed. Ultralisks gained an ability that allows them dash underground into the heart of enemy forces.[6]

NotesEdit

The visual effects of burrowing are limited as more fancy animations would take more time and thus lead to balance issues.[7]
