Lurker

Lurkers are a breed of Zerg which can attack from underneath the ground.

By the time of the Brood War, the Zerg had bred the Lurker from the Hydralisk. The Lurker burrows into the ground and attacks enemies above with a wave of subterranean spikes. The spikes do normal splash damage and are particularly effective against infantry. Unlike other Zerg units, the Lurker can only attack while burrowed. Burrowing does not need to be researched for the Lurker to burrow. If the Lurker is above ground, they gain mobility, but become defenseless.

Burrow

 * Starting ability

This allows the Lurker to hide underground so he can only be attacked while not being seen exept by detectors. This functions just like the the normal burrow (exept the Lurker can attack) however the Lurker can use it even if it has not been researched.

Upgrades

 * Missile Attacks
 * Carapace
