Infested (Heart of the Swarm mission)

Infested is the first of the Skygeirr Missions in Heart of the Swarm.

Summoned by Alexei Stukov, an infested terran and old enemy, Sarah Kerrigan brought the Swarm to Skygeirr and agreed to aid Stukov in destroying it. Stukov regarded the station as second most strongly-defended point in Dominion space.

The Swarm struck toward the entrance to the station's interior, augmenting itself with infested terrans created from infesting the garrison with infestors. The defenders used poison gas to periodically cull the newly infested terrans; the gas reserves took time to regenerate, allowing the Swarm to to advance and take over more garrisons as the chemicals were manufactured.

The external defenses were defeated and the Swarm gained access to the laboratories within.
