A dirty great big gate of the Zerg that has huge claws rise up from the ground before interlacing with each other to form an arch before huge tendrils shoot up from the ground to prevent units from passing. Comes complete with sounds and a glowing emblem to show it is locked. Currently only set up to let Zerg units (and nearby friends) past but can easily be modified to open and close on any desired condition (just alter the validator on the morph).
