StarCraft: Brood War Zerg structures like Hatchery, Extractor, and Spawning Pool. Learn costs, prerequisites, and upgrades.

Hatchery

The Hatchery represents the epicenter of the Zerg swarm. Here, the Drones are produced and any resources gathered are transferred to. The Hatchery also produces creep, the essential living ground that Zerg structures cannot be built without. The Hatchery can be upgraded into a Lair and Hive.

• Cost: 300 Minerals
• Hit Points: 1250
• Produces: Drone (Cost: 50 Minerals)
• Upgrades: Burrow (Cost: 100 Minerals/100 V.Gas)

Extractor

When an Extractor is built over a Vespene Gas geyser, the resource becomes accessible to your Drones. Harvested Vespene Gas will then be transferred to the nearest Hatchery/Lair/Hive.

• Cost: 50 Minerals
• Prerequisite/s: Hatchery
• Hit Points: 750

Spawning Pool

The Spawning Pool is a very important early-game structure. For starters, it allows the Hatchery to morph into a Lair. It's also responsible for Zergling upgrades as well.

• Cost: 200 Minerals
• Prerequisite/s: Hatchery
• Hit Points: 750
• Upgrades: Metabolic Boost (Cost: 100 Minerals/100 V.Gas), Adrenal Glands (Cost: 200 Minerals/200 V.Gas)

Hydralisk Den

As the name implies, the Hydralisk Den is responsible for all Hydralisk upgrades. Once this structure is built, you will be allowed to produce Hydralisks.

• Cost: 100 Minerals/50 V.Gas
• Prerequisite/s: Spawning Pool
• Hit Points: 850
• Upgrades: Muscular Augments (Cost: 150 Minerals/150 V.Gas), Grooved Spines (Cost: 150 Minerals/150 V.Gas)

Evolution Chamber

The Evolution Chamber provides the upgrades for all ground units. Due to its relatively low cost, it's strongly suggested that you construct more than one to greatly speed up the upgrading process.

• Cost: 75 Minerals
• Prerequisite/s: Hatchery
• Hit Points: 750
• Upgrades: Melee Attacks (Level 1: Cost - 100 Minerals/100 V.Gas, Level 2: Cost - 150 Minerals/150 V.Gas, Level 3: Cost - 200 Minerals/200 V.Gas), Missile Attacks (Level 1: Cost - 100 Minerals/100 V...Gas), Zerg Carapace (Level 1: Cost - 150 Minerals/150 V.Gas, Level 2: Cost - 225 Minerals/225 V.Gas, Level 3: Cost - 300 Minerals/300 V.Gas)

Creep Colony

Apart from the Hatchery, the Creep Colony is the only other structure that produces and extends the creep, the essential living ground that other structures must be built on. Creep Colonies are also responsible for morphing into static defense systems should they be needed.

• Cost: 75 Minerals
• Prerequisite/s: Hatchery
• Hit Points: 400

Sunken Colony

Sunken Colonies are a static defense mechanism that attacks only ground units with a deadly subterranean tentacle. Although it acts as static defense, the Sunken Colony is not a detector and cannot reveal cloaked or burrowed units.

• Cost: 50 Minerals
• Prerequisite/s: Pre-existing Creep Colony, Spawning Pool
• Hit Points: 300
• Ground Attack: 40

Spore Colony

Spore Colonies are essentially air defense fortifications. Their spores can rip apart enemy air units in seconds, especially when they're built in tight clusters. Spore Colonies are also detectors, meaning that they can detect invisible units. For that reason, Spore Colonies should be placed along the outskirts of bases.

• Cost: 50 Minerals
• Prerequisite/s: Pre-existing Creep Colony, Evolution Chamber
• Hit Points: 400
• Air Attack: 15

Lair

The Lair is the upgraded form of the Hatchery. It's more durable and comes with three special upgrades specifically made for Overlords. Upgrading a Hatchery to a Lair is a must in medium to long games.

• Cost: 150 Minerals/100 V.Gas
• Prerequisite/s: Pre-existing Hatchery, Spawning Pool
• Hit Points: 1800
• Upgrades: Antennae (Cost: 150 Minerals/150 V.Gas), Pneumatized Carapace (Cost: 150 Minerals/150 V.Gas), Ventral Sacs (Cost: 200 Minerals/200 V.Gas)

Spire

Apart from allowing you to create Mutalisks and Scourges, you can upgrade flyer weapons and carapaces as well. The Spire can be eventually be upgraded into a Greater Spire once requirements are met.

• Cost: 200 Minerals/150 V.Gas
• Prerequisite/s: Lair
• Hit Points: 600
• Upgrades: Flyer Attack (Level 1: Cost - 100 Minerals/100 V...Gas), Flyer Carapace (Level 1: Cost - 150 Minerals/150 V.Gas, Level 2: Cost - 225 Minerals/225 V.Gas, Level 3: Cost - 300 Minerals/300 V.Gas)

Queen's Nest

The Queen's Nest is one of the most important Zerg structures.

• Cost: 150 Minerals/100 V.Gas
• Prerequisite/s: Lair
• Hit Points: 850
