Where the Lords of Cthul stride into battle, reality warps and bends before tearing asunder. Void Gates are like wounds in the very fabric of the time-space continuum, and through them come otherworldly horrors to ravage the Earth. It is a top priority of all of Earth's defenders to eradicate these unnatural structures as rapidly as possible.
The Void Gate building manipulates allied and enemy units and helps deploy Lords of Cthul forces. A Destroyers player who secures this building can spawn Lords of Cthul units to the battlefield cheaper. Any player who secures this building gains the ability to promote grunt units into elites and to move nearby units.
