⚠ Major post-game / ending spoilers.
Big Game
Big Game is Big Walk’s later completion achievement. It comes after Big Goodbye and it is awarded when you complete the second-ending flow.
Big Game is Big Walk’s later completion achievement. It comes after Big Goodbye and is awarded when you complete the second-ending flow.
Finish Big Goodbye first. Then continue the same save, follow the unlocked post-game route and complete the second ending. The achievement registers when that ending flow finishes.
They sit on the same progression path. Big Goodbye is the main ending; Big Game is the later full-completion ending. They are sequential, not a choice.
Big Goodbye
Main ending. The post-game still remains after it.
Big Game
Post-game / full-completion ending. This is the later achievement.

Big Game is not the same thing as simply reaching 100% on a local checklist. The ending flow still has to complete.
Pick the state that matches your save. Each answer stays inside what the current build closes and hands the rest to its owner page.
Your current state
這是本站已經完整閉合的進度主線。通往第二結局的每一步都是一道關卡；大玩一番本身則是完成結局的獎勵。
社群攻略一致反映，清掉剩餘的謎題和紫色挑戰是有影響的。只有在完成條件已經完全確認的地方，本頁才會給出確切的必做數量。
Tick what is already true on your save. The page points at the next open step.
Finish Big Goodbye first, then come back to this page.

Big Game is awarded from the second-ending completion flow. The production data shows the achievement unlock being called when you continue from the Ending 2 completion screen.
Closed gameplay unlock hook:
This is the normal ending completion flow, not a special button. Finish the ending normally rather than quitting as soon as the final scene starts.
Functionally, Big Game is the game’s full-completion ending achievement, and current community guides consistently tie it to clearing the remaining main-game and post-game content.
For this site, the exact checklist stays owned by the 100% tracker. Only requirements closed by current game-data dependencies are labelled mandatory here.
So: Big Game behaves like a full-completion ending, but the mandatory count is not published as a serialized fact until the completion dependency closes.
These three groups are kept apart on purpose. The page never presents the community checklist as verified game data.
Reported consistently by independent guides, but not closed as a dependency edge here.
Until the completion dependency regression closes them, these stay off the mandatory list: exact mandatory puzzle count, exact Purple count as a dependency edge, exact required collectible total, exact required achievement count and the exact Overflow release threshold.
The Overflow Key is not another normal coloured five-cutter Big Key. It arrives finished from its own post-game state.
Do not take it to the ordinary five cutters.
Community aliases: final key / true-ending key / white key. This site uses Overflow Key.
Open the Overflow MonumentWork down this order before replaying any completion content.
1. Did you actually reach the second ending?
The Overflow Key is not Big Game. Holding the key is an earlier state.
2. Did you finish the second-ending flow?
Starting the second ending is not the medal completion hook. Finish the flow.
3. Do not quit at the first final scene
Let the normal ending completion and menu flow finish.
4. Check the platform achievement list
A missing toast is not proof the medal did not register.
5. Continue on the same host save
Post-game is a same-save continuation, so a different journey will not carry it.
If you already finished the Ending 2 completion flow and only the external list is empty, the remaining problem may be platform-side achievement sync.
A completion checklist being full is not itself the Big Game trigger.
Big Game is the Ending2 achievement, so you still need to follow the unlocked post-game route through the Overflow Key and the second ending, then finish that ending flow.
先完成盛大道別，繼續同一段通關後旅程，走完第二結局路線並完成那個結局的流程。大玩一番已確認的觸發點是 Ending2 的完成選單。
社群攻略反映，清掉剩餘的謎題很重要。本頁只在依賴關係已確定的地方把要求標為必須，所以目前還沒有把確切的謎題數量作為硬性門檻公布。
官方的說法是「完整通關遊戲」，而不是「解鎖其他所有成就」。目前沒有經過驗證的證據顯示，無關的遊玩成就本身是大玩一番的直接門檻。
不需要。它的路線用到的切割機數量為零，而且是從它自己的通關後狀態裡直接以成品形式出現。
第二結局路線及其目的地的名稱，而不是成就的名稱。
不是。第二次道別是結局 / 目的地的標籤；大玩一番是那個結局流程結束時授予的成就。
完整的清單並不是觸發條件。大玩一番是 Ending2 成就，所以你仍然需要完成通關後路線，並走完第二結局的流程。
把結局的完成流程走完，並在完成畫面之後繼續，不要在第一個最終場景就退出，然後再檢查一遍平台的成就清單。
