[edit] Development

Overseers used to have similar special abilities as the overlord, but those were removed.^[6][17]

• Excrete Creep^[18]
  • The overseer can create a small patch of Creep,^[19] the radius steadily expanding as long as it remains stationary.^[20][21] This ability is researched at the Evolution Chamber.^[22]

• Slime (also known as "Corrupt Minerals")^[7]
  • The overseer can drop a non-attacking slime creature,^[21] temporarily disabling resource nodes and xel'naga towers.^[19][23] The slime can be attacked and removed by other forces.^[20] The minerals can be covered as they're being harvested, enabling raids which slow down an enemy's economy. The creature must be killed before the minerals can be accessed.^[21]
  • This ability took time to "cast" and had a small cooldown timer.^[21]

Spore Cloud
Usage Energy 50[10]
Notes
The overseer can create a Spore Cloud, which covers an area, blocking line of sight for a period of time. Units above the fog can see over and into it.[10]
Edit

Removed as of August 2009.^[14]

[edit] Notes

The overseer was developed as the universal overlord detection in StarCraft I made the zerg "detectorific". As such, the overlord/overseer split makes cloaking more useful to a zerg's opponent.^[20]
