Infestors are one of the more insidious new additions to the Swarm. They were evolved from the Borbu Matriarch, an unusual creature that is more like an ambulatory nest than a single organism. Unlike most Zerg warriors, Infestors have the ability to move while burrowed. These terrors can spew a volatile plague over their targets with dire effects, and they have been known to ingest Infested Marines, carry them to a combat zone, and regurgitate them to fight for the Swarm. Perhaps the Infestor’s most dangerous feature is the Neural Parasite, a symbiotic creature living within Infestors that, when spat, attaches to an enemy and controls its mind for a short period of time. Seeing the immense potential of this parasite, the Queen of Blades is busy incubating new strains that can live longer outside of their host.

SPECIMEN ANALYSIS

The sole purpose of this flexible appendage is to bore through natural or artificial plating in order to inject a neural parasite directly into the victim’s nervous system. The amorphous, multi-mouthed parasite cannot survive for long within a foreign body, but whatever horrific deeds the host carries out while under the influence of the Swarm will leave everlasting scars.

Hardened plates of assimilated mold and fungus offer protection from enemy fire and would-be predators. This peculiar “armor” also functions as a weapon. The Infestor can turn the inner layer of its carapace into a viscous fluid that breaks down matter in seconds and immobilizes anything it comes in contact with.

Evolution and adaptation have done wonders for the Borbu Matriarchs. Their sturdy legs secrete a corrosive substance that softens the soil and allows them to burrow in the blink of an eye.

These abominations are known to ingest infested terran marines to use as terror weapons on the battlefield. The twisted marines are stored in thick flesh cavities until the Infestor regurgitates them to face their former compatriots—or anything else that might pose a threat to the Swarm.

These writhing feelers serve as a secondary, albeit more powerful, set of eyes and ears by means of thousands of microscopic growths that function as biological “transceivers”. Further research on the subject has been slow and fruitless.

General Strategy

Ground support unit.
Can burrow with Burrow upgrade.
Can move while burrowed, but cannot use Fungal Growth or Neural Parasite while burrowed. Infested Terran can be used while burrowed to launch surprise attacks against enemy workers or structures.
Neural Parasite ability allows the Zerg player to steal and use enemy units. This even affects enemy workers, allowing the Zerg to build other races’ buildings.
The Pathogen Glands upgrade allows Infestors to be spawned with more energy for activating abilities.
Effective at stopping fast-moving units by snaring them in place and dealing damage with their Fungal Growth ability.

Evolutions

Burrow: Allows the unit to take cover underground, rendering it unable to attack. A burrowed unit is invisible unless revealed by detectors or effects.
Pathogen Glands: Increases infestor starting energy by 25.
Neural Parasite: The infestor can take control of enemy units.

Countermeasures

Terran VS

Use Ghosts’ EMP Round ability to drain Infestors’ energy.
Detect and destroy Infestors quickly with Ravens using the Seeker Missile upgrade.
Use long range weapons such as Siege Tanks to focus-fire Infestors down.
Use the Orbital Command upgrade to scan for and reveal burrowed Infestors.

Zerg VS

Infestors can be defeated by ranged anti-ground units like Hydralisks and Roaches that can continue attacking while affected by the Fungal Growth ability.
Use Overseers to detect Infestors for your army to kill.
Bring enemy Infestors under your control by employing your own Infestors with the Neural Parasite upgrade.

Protoss VS

The High Templar’s ’Feedback’ ability does immense, instantaneous damage to Infestors.
Use siege range weapons such as Colossi to focus-fire Infestors down.
