The Nydus Worm is a Zerg structure used to move units quickly around the map.
After the Nydus Network is created, you can build a Nydus Worm anywhere where you have vision without the need for Creep or a Drone. The Worm takes 14 seconds to be set up, before emerging from the ground and settling into position. During this set up phase it has 3 armor. Once in position, it acts as an exit to the Nydus Network, allowing the player to transfer units from the Network to the Worm exit almost instantly. Upon completion of the Nydus Worm, a global sound effect will be heard from all players. Once the Worm is completed, it cannot be relocated and will act as an immobile structure.
