How Many Endings Does Big Walk Have?
Big Walk has two sequential completion endpoints on the same save: Big Goodbye first, then Big Game after further post-game completion. They are not mutually exclusive choices.
- Big Goodbye
- Post-game
- Big Game
| Ending | When | Game wording |
|---|---|---|
| Big Goodbye | Main journey | Finish the game |
| Big Game | Later completion | Completely finish the game |
The later ending starts from the same save file, so you can keep playing toward it after the first credits.

Big Goodbye — The Main Ending

What Do I Do With the Ending Key?
The Ending Key comes from the Black Tower late-game route and is already finished when you are awarded it. Unlike the coloured-route Big Keys, it does not use five cutters, so it goes straight to its destination.
Ending plinth
A finished key stays a route blocker until it reaches its destination. For the Ending Key that destination is the Ending plinth, and the Ending Gate opens from that plinth.
Ending Gate and the final sequence
The gate opens once the Ending plinth is active. Behind it is the final sequence that ends in Big Goodbye.
The seven Black Sphere rooms are not a room-count requirement for the gate, and their exact relation to the final sequence is not confirmed yet.

After Big Goodbye
Finished Big Goodbye?
Your main journey is complete. The same save continues into a separate post-game progression route.
○ Big Goodbye — Main journey complete.
The post-game route is the next thing to follow, not cleanup.
Big Game — The Later Completion Ending
Often searched as the “true ending”
Achievement: Completely finish the game
Finish Big Goodbye first. After that, continue on the same save. When your post-game completion state is ready, the later key route leads to Big Game.
Next objective: Start the post-game route once Big Goodbye is confirmed.

Post-game route
What exactly has to be finished first is still being verified, and guides count it differently, so follow the route rather than a reward number.
If your real question is what you are still missing, the 100% tracker answers that instead.
Ending Key vs Overflow Key
The two late-game keys are separate business, and neither one is a stage of the ordinary Big Key.
| Ending | Stage | Source | Cutters | Purpose | Detailed route |
|---|---|---|---|---|---|
| Ending KeyOlder guides also call it the Black Key or the final key. | Main ending | Black Tower reward | None | Opens the main ending route | Endings and Black Tower |
| Overflow KeyPlayers also call it the White Key or the true-ending key. | Post-game | Overflow Monument | None | Opens the later ending route | Post-game |
Why Can't I Finish the Ending?
Pick what you are seeing. Each answer checks the late-game steps in the order they happen and points at the guide that solves it.

후반 루트에 갈 수 없어요
What this usually means
주요 루트가 먼저예요. 검은 탑은 챌린지 개수가 아니라 월드 진행으로 열려요.
What to check
- • 주요 색깔 루트가 각자의 목적지에 모두 도착했나요?
- • 도개교 너머의 더 넓은 섬이 열려 있나요?
What to do
주요 루트를 끝낸 다음 후반 루트로 돌아오세요.

Big Walk Ending FAQ
- Big Walk에는 엔딩이 몇 개 있나요?
- 차례로 이어지는 완료 지점 두 개가 있어요: 빅 굿바이와 빅 게임. 빅 굿바이는 메인 게임의 마무리이고, 빅 게임은 엔딩 후 내용을 더 완료한 뒤에 와요.
- 빅 게임이 진엔딩인가요?
- 플레이어들은 보통 진엔딩이나 비밀 엔딩이라고 불러요. 게임 안에서는 빅 게임이라는 업적이며, 게임을 완전히 끝낸다는 뜻이에요.
- 빅 굿바이와 빅 게임 중 하나를 골라야 하나요?
- 아니요. 같은 저장 데이터에서 순서대로 일어나고, 첫 번째를 끝내도 막히는 것은 없어요.
- 빅 굿바이는 어떻게 달성하나요?
- 후반 진행을 마치고, 검은 탑 보상에서 엔딩 열쇠를 받아 엔딩 받침대에 놓은 뒤, 엔딩 게이트를 열고 그 너머의 시퀀스를 끝내세요. 빅 굿바이 루트
- 엔딩 열쇠에 커터가 필요한가요?
- 아니요. 받을 때 이미 완성된 상태라서 커터 루트가 없어요. 커터 다섯 개를 거치는 과정은 일반 색깔 루트에 해당해요. Big Key 가이드
- 엔딩 게이트가 왜 계속 닫혀 있나요?
- 여는 것은 받침대예요. 완성된 엔딩 열쇠는 놓기 전까지 계속 루트를 막고, 방 개수만으로는 게이트가 열리지 않아요. 엔딩 게이트 확인
- 빅 굿바이 이후에는 뭘 해야 하나요?
- 같은 저장 데이터로 엔딩 후를 이어서 진행하세요. 오버플로 연쇄가 거기서부터 후반 엔딩으로 이어져요. 엔딩 후 가이드
- 빅 게임에 100%가 필요한가요?
- 빅 게임은 게임을 완전히 끝내는 것과 연결되어 있고, 자세한 완료 체크리스트는 엔딩 후 가이드와 100% 가이드에 있어요. 보상 개수 하나가 아니라 그 트래커를 따라가세요. 100% 트래커
