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.
Many zerg ground units may burrow, rendering themselves invisible but incapable of moving or attacking.
Unlike other units, lurkers may burrow without the ability being researched.
- Roach, which may move while burrowed
- Lurker, which may attack while burrowed
- Infestor, which may move and cast Infested Terran
- Baneling, which can detonate while burrowed.
Some units can unburrow via autocast, causing them to emerge and attack when an enemy moves into range.
The ability is not smartcast.
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.
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. Similarly, the Perdition turret retracts automatically, when not in combat.
Heart of the Swarm 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The following section contains information from a previous version of StarCraft II: Heart of the Swarm which is no longer valid.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.
The visual effects of burrowing are limited as more fancy animations would take more time and thus lead to balance issues.
