Like the Zerg unit list, this is not necessarily the final set of structures players should expect to see in the game. In fact, as Blizzard tells it, this is very likely to change, so we’ve left off the build requirements for each building. We have, however, listed each structure’s name, function, and upgrades it makes available.

Overall there’s nothing particularly thrilling about the building list, with the possible exception of the Nydus Warrens and how they interact with the Nydus Worms. Other than that, the information below should be very recognizable to any StarCraft veteran. Note that we’re only counting buildings created by Drones. The base defenses Queens can erect are over on the unit list.

Hatchery – The Zerg main base. Can be upgraded to the Lair and Hive. Serves as the location where larva spawn and where the queen can be constructed.

Lair – Tier two Hatchery. Offers upgrades to Overseer (increased armor) and Overlord (increased armor and speed).

Hive - Tier three Hatchery. Necessary for unlocking all build and upgrade options.

Spawning pools – Lets you build Zerglings and offers Zergling upgrades (increased movement speed).

Extractor – Built on vespene gas deposits to make them accessible for mining.

Evolution Chamber – Contains research upgrades for burrow (unlocks burrow), slime (Overlord), generate creep (Overlord – this ability also increases Zerg buildings’ creep generation speed), and lets you upgrade the queen’s creep tumors to shriekers.

Roach Den – Enables the spawning of roaches, and contains roach upgrades (increased attack and armor ).

Nest – Lets Zerglings morph into Banelings, contains Baneling upgrades (increased weapons and armor).

Hydralisk Den – Enables the spawning of Hydralisks, contains Hydralisk upgrades (increased attack and armor), can mutate into a deep warren. Once a deep warren is created, you can access a Lurker upgrade (increased weapons and armor).

Spire – Allows for the spawning of Mutalisks and Corruptors. Contains Mutalisk upgrades (increased weapons and armor) and Corruptor upgrades (increase weapons and armor). Can be upgraded to a Greater Spire.

Greater Spire – Unlocks the Swarm Guardian and opens up Swarm Guardian upgrades (increased weapons and armor).

Nydus Warren – Enables the spawning of Infestors and Nydus Worms. Friendly units can use the Nydus Warren to instantly travel to any other Nydus Warren or Nydus Canal owned by that player. Also offers spell upgrades for Infestors.

Ultralisk cavern – Lets you create Ultralisks and offers Ultralisk upgrades (increased weapons and armor).
