Flood colony

The colony is a Flood structure that gestates Flood infection forms and stores combat forms. Their only known use was during a battle on a Flood-controlled Shield World in February 2531, when several such colonies were used to empower the local proto-Gravemind. These colonies were killed when the proto-Gravemind was destroyed.

Gameplay
In the campaign, the colony form cannot be completely destroyed; it can only reduced to a "dormant" state, from which it will soon recover. However, in multiplayer featuring, colony forms can be permanently killed. They can also be killed if a Proto-Gravemind is in the level, as destroying it will kill all the colonies, but this will mean little as the player will have beaten the level by doing so anyway.

Trivia

 * On the level The Flood, the Sweet Naptime achievement can be unlocked by putting all the colony forms into hibernation status simultaneously.
