The infested starport allows Stukov to construct infested liberators, infested banshees and brood queens, and possessing one enables Stukov's overlords to transform into overseers. Unlike the terran starport, units are spawned based on charges, with the structure able to store five charges of a unit. The infested starport can construct the infested tech lab as an add-on, allowing for production of infested banshees and brood queens as well as the purchase unit upgrades.
