Ghost (StarCraft II)

Ghosts are feared terran covert operatives. They are known for their skill, psionic powers and ability to cloak.

Game Unit
Ghosts take up two slots in a bunker.

Ghosts make good counters against mutalisks, but not against a zerg force as a whole.

Blizzard Entertainment is planning on giving them lore-based abilities from novels, graphic novels and a previous project.

Strategies
Ghosts can drop nukes very quickly. When backed up by medivac dropships, they can be moved from one strike zone to another, and heal the cloaked ghost whenever it gets attacked.

Development
Ghosts used to possess these abilities.
