Infestor

The Infestor is a Zerg unit set to appear in StarCraft II.

Overview
The Infestor is a replacement for the Defiler, retaining its predecessor's Dark Swarm ability. It cannot attack but is capable of moving while burrowed.

Abilities

 * Burrow
 * Main article: Burrow


 * Like many ground units, the Infestor can burrow. However, the Infestor can move while burrowed, enabling it to travel underneath defensive structures and attack from within a base.


 * Dark Swarm
 * This ability is automatically researched.
 * Dark Swarm works similarly to the Defiler's version, creating a smokescreen for units to hide under, protecting them from ranged attacks.
 * Dark Swarm protects units from a Ghost's Snipe attack as well.
 * A Roach's attacks are unaffected by Dark Swarm.
