Steam Achievements in The Carcass

The Carcass ships with 100 Steam achievements on the full release (the demo tracks a subset for testing progression). They nudge you toward behaviors the colony sim hides in prose: feed everyone, explore every region, befriend ten species, survive famine without collapsing. This guide groups trophies by intent so you can hunt them without spoiling secret endings or wall-voice chains.

Colony size achievements

Population trophies reward stable economies—not rush builds. Standard route:

1. Secure biomass with Nutrient Vats (buildings guide)
2. Avoid morale collapses during growth (citizens)
3. Batch free actions, end Pulses deliberately (Pulse guide)

Extinction difficulty still counts population achievements but gives less margin for error—see difficulty tier list.

Diplomacy achievements

Beloved of All demands +50 relations with ten different species—a marathon, not a sprint. Accept refugees when safe, honor blood pacts, avoid betrayal until you finish the counter. Pair with diplomacy research paths in research tier list. Friend of the Marrow style trophies focus on max relations with specific species like Marrow Dwellers—read event outcomes in events guide before auto-refusing strangers.

Exploration achievements

Legendary Pilgrim tracks legendary locations (demo UI references seven as a milestone). Regional Master requires every region visited—use a exploration journal and budget Pulses for travel instead of combat spam. Map details in map and regions.

Famine and endurance

Some achievements reward surviving crises—intentional or accidental. Keep emergency biomass stores before experimental harvests in red zones. If aiming for positive trophies, avoid triggering Famine failure states; if hunting completionist, read Steam description carefully for inverted goals.

Ironman, NG+, and achievements

Ironman does not block achievements unless Steam specifies otherwise. NG+ can speed diplomacy and exploration replays by carrying memory—consult New Game Plus before deleting saves. Cloud sync via Steam Cloud keeps achievement state across PCs per store features on release info.

Demo vs full game

Demo achievement progress may differ from full app ID 4315550. Link Steam accounts normally; buying the full game merges platform stats when Valve rules allow. Always verify on your library page.

Hunting without spoilers

• Use Steam global achievement percentages to gauge rarity
• Avoid wiki ending spoilers until story achievements done
• Track Pulse numbers when choices affect relations
• Watch launch day updates for achievement bugfixes

• Command lookup — navigation verbs for exploration
• Review — is completionism worth your play style?

One hundred achievements mean one hundred excuses to role-play a bureaucrat inside a corpse. Pick tracks that match your ending goal, not every trophy at once.

Completionist route order

Normal clear → map/exploration run → diplomacy marathon → Ironman specialty. Splitting goals reduces save scumming temptation.

Closing tips for hunters

Check Steam global stats before forcing famine trophies—some require failing forward intentionally.
