Creep Colonies help extend the Creep that is initially generated by a Hatchery. They also have the ability to evolve into a Sunken Colony (for repelling ground invasion) or into a Spore Colony (for repelling aerial assaults). The Creep Colony is not only necessary to expand the life-giving Creep but also for defense.
