The infestor takes control of target enemy unit. Units maintain their upgrades and special abilities while controlled. Control reverts to the original player if the infestor is killed, when duration ends, or when the range between the infestor and the controlled unit grows too large.
Controlled probes and SCVs can build structures; the SCV will leave a structure unfinished if it reverts during the construction. Affected drones cannot mutate structures. Larva can be morphed, but hatched units return to enemy's control once the effect has worn off.
Affected units cannot be loaded into transports, and ability cannot be used on transports carrying units.
Ability can be used on enemy infestors. Units mind controlled by affected infestors remain under player's control for normal duration, even after affected infestors revert to opponent's control.
