The infestor extends a long tentacle, latching onto an enemy ground or air unit, which is then covered in green tentacles. This enables the infestor to control that unit, which changes to match the infestor's color. Units maintain their upgrades and special abilities while controlled by the zerg. Ground and air units may be controlled, but control reverts to the original player if the infestor is killed or once the duration passes. Units that move beyond the infestor's range revert to the original player's control.
