⚠ 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
这是本站已经完整闭合的进程主线。通向第二结局的每一步都是一道关卡；大功告成本身则是完成结局的奖励。
社区攻略一致反映，清掉剩余的谜题和紫色挑战是有影响的。只有在完成条件已经完全确认的地方，本页才会给出确切的必做数量。
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.
先完成盛大告别，继续同一段通关后旅程，走完第二结局路线并完成那个结局的流程。大功告成已确认的触发点是 Ending2 的完成菜单。
社区攻略反映，清掉剩余的谜题很重要。本页只在依赖关系已确定的地方把要求标为必须，所以目前还没有把确切的谜题数量作为硬性门槛公布。
官方的说法是“完整通关游戏”，而不是“解锁其他所有成就”。目前没有经过验证的证据表明，无关的游玩成就本身是大功告成的直接门槛。
不需要。它的路线用到的切割机数量为零，而且是从它自己的通关后状态里直接以成品形式出现。
第二结局路线及其目的地的名称，而不是成就的名称。
不是。第二次告别是结局 / 目的地的标签；大功告成是那个结局流程结束时授予的成就。
完整的清单并不是触发条件。大功告成是 Ending2 成就，所以你仍然需要完成通关后路线，并走完第二结局的流程。
把结局的完成流程走完，并在完成画面之后继续，不要在第一个最终场景就退出，然后再检查一遍平台的成就列表。
