The spores can carry genetic information, and can be launched into space toward other zerg-inhabited planets.
A number of them were present during the Siege of Cask, where they were used for the transmission of genetic information, not combat, and in the defense of Char, where they were used for destroying Dominion spacecraft and structures.
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.
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.
