Unit profile from StarCraft: Remastered

Observation drones appear in the bonus map Deception. They are represented by the science vessel, though do not use any abilities apart from detection.

Should a drone be attacked, it will automatically retreat from the source of fire. After a while, it will return to its pre-established patrol route.


This unit may detect cloaked and burrowed enemies.
