StarCraft/Zerg buildings

Hatchery
The Hatchery is the Zerg's primary building, it produces creep on which other Zerg structures can be built as well as larvae. Larvae can be morphed into other units. Up to three larvae will spawn near the Hatchery. The Hatchery is required to build Lair, Extractor, Evolution chamber, Creep colony and Spawning pool.
