Omega Swarm

The Omega Swarm (also spelt Omegaswarm) was a zerg brood that was initially under the control of the United Earth Directorate on Braxis. The brood was subjected to controls, with armor welded into their carapaces. After the destruction of the psi disrupter, the zerg turned on their former masters, prompting a group of soldiers to fight their way to an extraction point.
