Flood launcher

The Flood Launcher is a Halo Wars Flood Building.

Description
It fires some form of flood-goo out of the whole at the top of the structure at enemy forces. In the level Shield World from Halo Wars, they are used as an anti-air unit, capable of shooting down the evac pelicans for Alpha, Bravo and Charlie Platoon. Like all Flood building forms in Halo Wars, it cannot be killed by conventional means, instead going into a dormant state from which it will soon recover. However on the multiplayer maps it can be killed completely. it looks very similar to the Unnamed Organic Tower-Like Form perhaps they are the same Building.
