Spoilers ahead. This checklist includes the normal ending, post-game purple remixes and the complete-ending trigger.
The cleanest 100% run has two passes: finish the story, then return for anything the first run skipped. Big Goodbye is the credits trophy; Big Game is the complete ending and requires full completion.
Core unlock checklist
- Big Walk — lower the starting drawbridge.
- Big View — open the map room through the red tower.
- Big Tunnel — enter the yellow tower's tunnel network.
- Big Ride — start and ride a train through the blue tower route.
- Big Sit — ride the green tower's chairlift.
- Big Climb — reach the island's highest point.
- Big Makeover — have a teammate paint one body section with metallic paint.
- Big Help — wear a hip item.
- Big Pack — wear a backpack.
- Big Wall — pass through the great wall during the endgame.
- Big Goodbye — reach the credits.
- Big Game — trigger the complete ending after every required cleanup.
The trophies and achievements page keeps the short descriptions and source links; this page is the run order.
Before entering the black tower
- All five colored tower keys are finished and used.
- The map, train and chairlift have each been tested.
- At least one backpack and one hip item have been worn.
- A teammate has applied metallic paint in the tunnel salon.
- Every puzzle your group skipped is written in a shared note.
- Everyone who wants the first ending is in the host's session.
After the credits
- Find and clear seven purple remix puzzles. Record each coordinate in the purple tracker.
- Revisit every skipped base puzzle and collect its red prize.
- Check the black-tower route and any missed map coordinate.
- Return the final key to the small black sphere in the tutorial area.
- Enter the secret room and watch the complete-ending sequence.
For a map-first cleanup, use the fast-travel route planner. If a puzzle is missing one piece rather than one entire reward, open the stuck-puzzle rescue index before restarting the island.
If Big Game does not pop
Do not immediately repeat the entire island. First compare the checklist with the host's world:
- Confirm all seven purple slots are marked after the final reward animation.
- Check for a skipped puzzle in each colored-tower page.
- Re-wear the backpack, hip item and metallic paint if a trophy was earned by a guest instead of the host.
- Reload the host session, return to the black sphere and interact again.
To be confirmed: the exact trigger order inside the secret room and how a future patch may handle a disconnected guest. The completion requirements above are based on the official trophy list plus independent ending walkthroughs.
The 15-reward cleanup reported by completionists
Recent completion reports say the purple rewards come from post-game remix puzzles and are placed in a separate room with the red rewards that the tower route did not need. Filling that room is reported to produce the final key used on the hidden-ending route, while the normal credits run can still skip puzzles.
This gives the 100% route a practical target: mark every purple reward and every skipped red reward before returning to the tutorial-area black sphere. The official FAQ confirms that Big Walk has a hand-crafted ending, but it does not publish the community room count.
To be confirmed: Community reports converge on 15 slots, but the split is not official: one early report says six purple rewards, while later full-completion reports say seven purple plus eight skipped red rewards. Keep that split To be confirmed.
