Big Walk Post-Game Guide
Finished Big Goodbye? Here's what to do next.
Your main journey is done and the same save keeps going. This page gives you one next objective at a time on the post-game route, and sends completion cleanup to its own tracker.
Can I keep playing?
Yes. Big Goodbye ends the main journey, but the same save continues into a separate post-game layer. Your next job is to start the verified Overflow progression route, while the Purple challenges and general 100% cleanup are tracked separately.
The Overflow route, Purple challenges and leftover completion are three different questions. This page only decides the next step on the post-game progression route.
Your Next Post-Game Objective
Tell me where you are
Pick whatever you have already done after Big Goodbye and I'll name the step in front of you. If Big Goodbye is not finished yet, start with the endings guide.
What Changes After Big Goodbye?
Four things change, and only the first one is a new objective.
The same save continues
Post-game is not a new game or a branch you missed. You keep the save you finished on.
Post-game progression starts
The Overflow chain becomes the thing to follow next.
Purple content opens
The Purple challenges belong to the post-game layer, and they are tracked as completion rather than as this route.
Big Game becomes the later goal
The later ending is the endpoint you are moving toward. Anything still missing around it belongs to the 100% tracker.
通關後路線一覽
這是已查證的通關後鏈條：一個來源、一把鑰匙，以及它在後期結局之前的目的地。
- 盛大道別
- 通關後內容開啟
- 溢出紀念碑
- 溢出鑰匙
- 第二結局底座
- 第二結局之門
- 後期結局
這條路線會通往一個後期結局狀態。大玩一番是對應該狀態的成就，所以本頁把路線名稱和成就名稱分開標示。
開啟通關後地圖Find the Overflow Monument
The Overflow Monument is the verified source of the post-game Overflow Key.
It is the first destination on the post-game chain, and it only becomes relevant after Big Goodbye. Reaching it is the step that puts the Overflow route in motion.
Show the Overflow Monument on the MapGet the Overflow Key
The Overflow Key comes from the Overflow Monument and belongs to its own post-game route.
Once you have it, the key still has to reach its destination before the later door reacts. Treat the key as a stage you are carrying, not as a finished task.
The Overflow Key arrives already complete: no cutters and no five-cutter colored route.
Is the Overflow Key the final key?
Players also look for this key under other names, so here is the split:
- Ending Key — Black Tower / Big Goodbye
- Overflow Key — post-game / later ending
Take the Overflow Key to Its Destination
The Overflow Key has a specific destination before the later door becomes available.
The key, the plinth and the door are three separate states, so a placed key does not always mean an open door. Work down the chain instead of replaying the route from the start.
- Overflow Key
- Second Ending Plinth
- Second Ending Door
The Second Ending Plinth is the destination. The Second Ending Door is what opens from it.

Pick what you are seeing. Each answer checks the post-game chain before it guesses at anything else.
What are you seeing?
我通關了「盛大道別」，但看起來沒有任何不同
What this usually means
通關後不是一個獨立的新遊戲分支。選單裡不需要出現任何新東西，這條路線就已經可用了。
What to do
繼續同一份存檔，去找溢出紀念碑。
Post-game content layer
Purple Challenges Also Open After Big Goodbye
The Purple challenges belong to the post-game content layer rather than to the Overflow chain. Their solutions and completion tracking live on their own page.
Purple ChallengesCleaning Up the Rest of the Game?
Post-game progression and full completion overlap, but they are not the same question.
Check Everything I'm MissingLater completion endpoint
Moving Toward Big Game
Big Game is the later completion endpoint this route moves toward, and it is also an achievement. The Overflow route is the part you can act on here; the exact full-completion requirement chain is diagnosed on the 100% tracker.
Post-game route status
Finish Big Goodbye first
The post-game route continues from the same save after the main ending, so it has not started yet.
Guides online count the requirement for Big Game differently, so treat the route as the map and the tracker as the checklist rather than trusting a single reward number.
