"The zerg planetary defenses are made up of spore cannons. They destroy targets entering the planet's orbit."

A spore cannon firing

Spore cannons are zerg structures which can fire globs of acid spores at land targets or at spacecraft in orbit.[1] They are powerful enough to act as siege weapons.

The spores can carry genetic information, and can be launched into space toward other zerg-inhabited planets.[2]


The spore cannon had been evolved by 2501. The Terran Dominion recognized them by that point.[3]

A number of them were present during the Siege of Cask, where they were used for the transmission of genetic information, not combat,[2] and in the defense of Char, where they were used for destroying Dominion spacecraft and structures.[1]

Game Unit[]

Spore cannons appear in the StarCraft II: Wings of Liberty mission, "Gates of Hell". Their attack launches into the air and disappears, making it purely cosmetic though the destruction of them leaves behind deposits of vespene gas for players to gather. Cut lines from the mission indicate that if the player destroyed the cannons, a bonus would be received.[4]

The cannon uses the same model as the virophage except the head of the former is angled upward and the head of the latter is level.


This unit or structure can detect cloaked, burrowed, duplicated and hallucination enemies.
