The Sunken Colony is the Zerg means of ground defense. Using deadly Subterranean Tentacles to suprise and puncture enemy ground based units, the Sunken Colony can quickly turn the tide of a battle. The best use of the Sunken Colony lies in building them in clusters and using them in conjunction with Spore Colonies since they have no detection abilities of their own and would be unable to defend against cloaked or burrowed units.
