The Zerg Lair is the 2nd major step in the evolution of the Zerg breeds. Morphed from the Hatchery, the Lair has many of the same characteristics (produces Larva and maintains the Creep) but also provides additional upgrades for the Overlord, which include the Ventral Sacs (transporting ability), Antennae (increased sight) and Pneumatized Carapace (faster movement).
