Mother Core

Mateřské jádro
View Mother Core

The living headquarters: produces Cultivators and receives harvested minerals.

350M30s1650HP
PRODUCESCultivator
When to use it

BRING IT WHEN

Keep worker production moving and protect at least one completed Mother Core.

KEEP IN MIND

Losing your last completed headquarters ends the match. A growing replacement does not count yet.

War Hatchery

Bojová líheň
View War Hatchery

The main ground-combat hatchery for Ridgebacks, Acid Spitters and Spinecasters.

155M15s900HP
PRODUCESRidgeback, Acid Spitter, Spinecaster
When to use it

BRING IT WHEN

Build a frontline, answer enemy armor and add early anti-air without advanced research.

KEEP IN MIND

Needs active connected living substrate and a clear exit. Each hatchery has its own paid production queue.

Metabolic Node

Metabolic Node

Metabolický uzel
View Metabolic Node

Starts an independent living organism: its active radius grows from 96 to 640 over 20 seconds.

100M10s400HP
INFRASTRUCTUREOperates independently
When to use it

BRING IT WHEN

Grow active ground under your first hatchery. At 75% growth the first developed site adds ten supply places.

KEEP IN MIND

Separated developed sites support supply and production. Severing a root immediately stops dependent branches; there is no energy budget.

Acid Spire

Žíhavá věž
View Acid Spire

A rooted defense organism dependent on active living substrate that attacks ground enemies near your base.

Attacks: Ground only

105M12s500HP
INFRASTRUCTUREActive connected living ground
When to use it

BRING IT WHEN

Protect an entrance or mineral line while the mobile army is away.

KEEP IN MIND

Cannot target aircraft and stops firing outside active living territory. Siege can attack from outside its range.

Malá líheň

A light support branch for Prowlers, Menders and Symbionts.

145M15s900HP
PRODUCESProwler, Mender, Symbiont
When to use it

BRING IT WHEN

Add reconnaissance and recovery early; unlock Symbionts after completing a War Hatchery.

KEEP IN MIND

Needs active connected living substrate and a clear exit. Support organisms need a fighting force around them.

Spore Chamber

Výtrusná komora
View Spore Chamber

An advanced production branch for Sporecasters, Mistweavers and Spewer backline firepower.

230M25s900HP25C
PRODUCESSporecaster, Mistweaver, Spewer
When to use it

BRING IT WHEN

Combine delayed siege impacts, movement control and protected acid salvos when advancing on ground forces.

KEEP IN MIND

Requires Specialized Production and a completed Gene Chamber. Its specialists need vision and protection.

Gene Chamber

Genová komora
View Gene Chamber

The research organ for Specialized Production, Logistics and Field Engineering.

180M20s900HP
INFRASTRUCTUREActive connected living ground
When to use it

BRING IT WHEN

Develop the technologies needed for advanced hatcheries, aerial forces and field specialists.

KEEP IN MIND

Needs active connected living territory and HQ Development for advanced unlocks. Srost research requires a Growth Node; losing the chamber does not erase completed research.

Supply

Growth Node

Růstový uzel
View Growth Node

Gradually extends connected living territory and out-of-combat recovery, and adds supply at separated developed sites.

65M10s300HP
INFRASTRUCTUREActive connected living ground
When to use it

BRING IT WHEN

Let the parent region reach the new node, then expand toward more territory. Separated, developed sites improve hatchery production.

KEEP IN MIND

Sites need 75% growth and 384 world units of separation to add ten supply places each. Cutting a connection immediately removes the branch’s operation, supply and recovery benefits. Overlapping nodes do not multiply recovery.

When to use it

BRING IT WHEN

Evacuate survivors in a Brood Carrier or prepare a short burrow transfer within living territory.

KEEP IN MIND

Requires Logistics, a Small Hatchery and Mother Core. Needs active living substrate and clear production exits.

When to use it

BRING IT WHEN

Hold enemies inside your spore fields or infect and weaken a dangerous combat unit.

KEEP IN MIND

Requires Field Engineering, a War Hatchery and a Gene Chamber. These specialists depend on careful positioning.

PRODUCESStinger, Blightwing
When to use it

BRING IT WHEN

Open an air route after Specialized Production and combine the two creatures according to the enemy’s targets.

KEEP IN MIND

Needs active living territory and advanced research. Flying units still need protection from fighters and anti-air.

A living-territory-dependent anti-air defense organism available without advanced research.

Attacks: Air only

125M15s450HP
INFRASTRUCTUREActive connected living ground
When to use it

BRING IT WHEN

Guard important hatcheries and harvesting lines against aircraft.

KEEP IN MIND

Targets aircraft only. Ground attackers and severed roots need a different defensive answer.

A worker-operated catalyst organ grown directly on a catalyst deposit.

100M12s600HP
INFRASTRUCTURECatalyst deposit + local HQ + workers
When to use it

BRING IT WHEN

Staff it with up to three Cultivators in a camp with a completed Mother Core before advanced research.

KEEP IN MIND

Shares the camp worker limit with minerals. Living territory does not create free resources; this is not a mineral receiver.

COMMANDER’S NOTE

Colonist buildings operate independently. Khars need direct resonance coverage; Srost needs connected living ground. Supply is separate, and paid queues reserve it immediately.
