The Carcass Colony Resources Explained

Colony survival hinges on four tracked resources—biomass, calcium, bile, and neurons. This page zooms into colony-side accounting: how structures consume them, how citizens deplete them, and how regions differ—companion to the resource management guide for Pulse strategy.

Biomass

Primary food analog. Citizens consume biomass each Pulse; negative turn reports mean ration events or famine soon. Sources:

• Harvest of organic regions
• Nutrient Vats converting raw organic input
• Trade from S-tier species (alien tier list)

Stabilize biomass before any military or forbidden research spike.

Calcium

Structural mineral from bone regions. Required for walls, Bone Quarries, and fortifications. Bottleneck symptom: construction queues paused with “insufficient calcium” prose.

Bone Quarries provide passive calcium; quarries plus targeted harvest beats over-harvesting dangerous marrow early.

Bile

Industrial fluid for forges, fermentation, and mid-game production chains. Less urgent than biomass/calcium but critical before mass forging.

Bile events sometimes offer moral choices—sell for food vs store for industry.

Neurons

Research currency from neural tissue, study events, and altars. Neuron starvation slows tech while parasites grow.

Studying forbidden organs trades immediate biomass for neuron floods—ending relevant (endings guide).

Regional yields

Procedural anatomy means regions rotate yields and danger. Labels in harvest menus post-2.0 show Pulse cost—never ignore red danger text.

Deep regions: higher neurons, higher parasite risk (combat guide).

Colony consumption table mindset

Think per Pulse:

Income (harvest + buildings + trade)
− Citizen food
− Construction projects
− Event losses
= Net (turn report)

If net biomass negative twice, emergency harvest or ration.

Storage and trade

No infinite warehouse fantasy—text reports imply margins. Trade treaties add income spikes; embargoes remove them abruptly.

Large populations

500+ citizens multiply consumption. Recommended PC spec exists for a reason (release info). Expand production before population boom.

Resources are the colony’s bloodstream—literally, inside a god.

Trade shock planning

Keep ten Pulses of biomass buffer before relying on faction imports. Embargoes after betrayal hit without warning.

Deep dive: economy loops

Biomass is the clock you hear ticking. Calcium gates expansion. Bile unlocks industrial mid-game. Neurons gate research and occult paths. Harvest menus post-2.0 label Pulse costs—never harvest red zones without combat readiness.

Trade can cover biomass gaps when diplomacy succeeds. Embargoes after betrayal remove safety nets—maintain internal vats before trusting imports. Studying organs trades short-term food for neuron spikes; Awakening players embrace this, Dominion players often harvest instead.

Turn reports are mandatory reading. If you cannot explain last Pulse deltas, you are not ready for Hard difficulty. Resource pages pair with Pulse system and buildings for full loop mastery.

Closing tips for economists

Neuron droughts hurt more than calcium droughts late. Study organs when research stalls, harvest when food stalls.

Player notes on Colony Resources

Veterans recommend revisiting this topic after the 2.0 patch because Pulse labels and harvest menus changed beginner muscle memory. Pair this page with the guides hub when planning multi-run completion. Ironman players should read related controls pages before committing single-save attempts. Document event choices with Pulse numbers when chasing secret endings or NG+ memory flags. Trade reliance fails after betrayal—internal Nutrient Vats remain the reliable backbone on Normal and Hard. Extinction difficulty punishes sloppy turn reports; scan biomass every Pulse without exception. Large populations above five hundred citizens require recommended PC specs listed on release info.

Continued study of Colony Resources inside The Carcass: cross-link tier list hub, colony hub, and updates hub so patch changes never invalidate your plan mid-run.

Closing tips for economists

neuron droughts hurt late game more than early calcium gaps. Study organs when research stalls; harvest when biomass stalls. Trade fails after betrayal—internal vats remain backbone. Read turn reports every Pulse on Hard or higher.
