The Overseer is a new unit to the Zerg swarm and its primary purpose is to provide Detection against hidden and hallucinated enemies. Overseers are unable to carry units like an upgraded Overlord, but they can create Changelings. Overseers also provide 8 Supplies for the swarm.
Instantly creates a Changeling that lasts for a limited time. Changelings are very weak creatures designed to spy on the enemy. When a Changeling approaches an enemy base or unit, it will instantly transform inself to blend it. The unit will transform into a Marine, Zergling, or Zealot to match the race and color of the enemy Player. This transform can only occur once during its lifetime and will appear as a friendly target to the enemy.
Changelings will only obey orders from the Zerg Player and cannot make any attacks while transformed. If the disguised Changeling is selected by the enemy Player, it will display the unit name as "Changeling" instead of the unit it mimics. This makes it easier for enemy Players to determine if the unit is theirs or not.
