Flood vent

The Flood vent is a Flood-infested Forerunner structure that gestates various airborne Flood forms. They are characterised by Flood tentacles and blisters occupying an artificial chasm. Such structures are only known to have been found during the battle on the Etran Harborage in 2531.

Gameplay
The Flood vent is a Flood-affiliated building that appears exclusively in the Halo Wars campaign level Beachhead. There are four Flood vents in the level, each occupying a corner of the map. Like the Flood colony, the Flood vent cannot be destroyed, but only reduced to a dormant status, from which it will soon recover. When active, the structure regularly produces infection forms, swarms, and bomber forms.
