Short answer
The 16 unlocks are Achievement Unlocked, Fatal Performance, No Strings Attached, System Override, Against All Odds, Escape, I Want To Be A Fisherman, Return, Footwork Master, Case Closed, Cut The Act, Short Circuit, Water Break, Stay, The Yeti, and A Natural Brawler. Back up before each boss and the late Chapter I branch so mutually exclusive outcomes do not require full replays.
When to do it: Start tracking in Mellow's opening room, create the major backup near the end of Chapter I, and finish cleanup before deleting any ending or boss-choice saves.
What you need: All three main ending routes plus The Yeti sequence, both outcomes for three major bosses, all 18 fish, 100 soccer hits, every gambler, three separate drinks, and 15 enemy defeats.
Missable or risky: Several are route-exclusive or tied to early activities. Footwork Master is safest at the opening; boss outcomes and endings require backups.
Confirmed details
Direct actions: click the poster for Achievement Unlocked; beat every gambler at dice for Against All Odds; catch all 18 named fish for I Want To Be A Fisherman; score 100 in the opening soccer minigame for Footwork Master; drink on three separate occasions for Water Break; and defeat 15 enemies for A Natural Brawler.
Boss pairs: defeat Trapezist for Fatal Performance or cut his leftmost rope with the scalpel for Cut The Act; defeat Chameleon for No Strings Attached or solve the Ollie/Ozzie dialogue for Case Closed; defeat the AI for System Override or use a filled cup on the outlet for Short Circuit.
Hidden story unlocks correspond to Escape, Return, Stay, and The Yeti. Complete the Toy Saw route for Escape, the real Saw route for Return, all three area secrets and epilogue return for Stay, then follow the unlocked Andy sequence for The Yeti.
This page separates documented requirements from route advice.

Step-by-step solution
Step 1 — In the opening, click the poster and finish the 100-hit soccer chain. During Chapter I, drink when offered, play every gambler, catch fish across all six clock states, and count unique/repeat fights toward 15 defeats.
Step 2 — Before Trapezist, Chameleon, and the AI, make separate backups. Earn each defeat achievement first, verify Steam recorded it, then restore and complete the peaceful environmental/dialogue route.
Step 3 — At the late Chapter I master backup, preserve Misery before everyone leaves, Timesville before its boss, and the Office before its boss while completing the three hidden area secrets on the Stay route.
Step 4 — Use the same master state to complete Escape with the Toy Saw and Return with the real Saw, confirming each hidden Steam unlock before restoring.
Step 5 — Finish Stay through the Chapter III epilogue by returning to Mellow's room instead of opening the obvious door. After the three main outcomes are recorded, complete the Andy sequence for The Yeti and compare Steam's list against all 16 names.
Common failures and softlock risks
The three peaceful boss achievements are not mercy commands during combat. Each requires an action before the fight begins.
The hidden labels on Steam intentionally conceal story conditions. Do not delete the master backup after only Escape and Return; Stay needs the three secrets on one route.
A Natural Brawler has launch reports of inconsistent counting. Preserve a save before optional fights and verify the Steam unlock instead of relying only on a handwritten total.
Recovery rule: stop before crossing another chapter boundary. Confirm the current objective, cycle every usable inventory item, and retry the interaction from a clean room entry. If the trigger still fails, close the game before restoring a known-good save; copying or replacing live save files while the game is open can overwrite the recovery state.
Version and verification
All 16 names and visible conditions were transcribed from Steam's global achievement page; hidden-ending mapping and boss branches were cross-checked against the launch all-endings and peaceful-route guides.
Last verified: July 31, 2026, against the launch PC build, Steam achievement records, linked Steam Community guides, and recorded full-game footage. Endacopia can vary some puzzle clues between runs, so follow the clue in your own save when this page explains a method instead of a fixed answer.
Frequently asked questions
How many achievements does Endacopia have?
The launch Steam build has 16 achievements, including four hidden story outcomes and six paired boss outcomes.
Can I unlock every achievement in one save file?
Not as one uninterrupted timeline. Use backups before the three boss choices and late Chapter I ending branch, while Steam retains each account unlock.
