Flame turret

Flame turrets are automated terran static turrets that rotate and spew flames. They also have the ability to detect cloaked units.

Nova Covert Ops
Flame turrets appear during the mission "The Escape" of Nova Covert Ops. They rotate and spew flames in a line, damaging Nova and any allied ghosts caught in it for 20 damage per second. This can add up, partiularly in sections where marauders slow Nova down. Flame turrets are invulnerable, and unlike gun turrets cannot be deactivated.
