Big Walk hides a second ending behind the one most players reach first. Rolling the initial credits only closes out part of the game, and the Big Game trophy, which rewards full completion, stays locked until you clear every puzzle in the world. Getting there means finishing content that opens up only after the first ending plays.
Quick answer: Complete every puzzle in the game, including the seven purple puzzles that unlock after the first ending, collect the final key that rises from the ground, then enter the secret room near the spawn area and read the messages inside to trigger the true ending. The Big Game trophy unlocks at that moment.
Big Walk has two endings
There are two endings in total. The first one is the one most players will reach just by working through the main path. The second is the true, full ending, and it is gated entirely behind 100% puzzle completion. The Big Game trophy is tied to that second ending, not the first.
This matters because the game has two separate completion trophies. Big Goodbye unlocks when you finish the game the first time. Big Game unlocks only when you completely finish it, meaning every puzzle done, the final key used, and the true ending triggered.
| Trophy | Requirement | Grade |
|---|---|---|
| Big Goodbye | Finish the game (first ending) | Gold |
| Big Game | Completely finish the game (true ending) | Gold |
Reach the first ending first
You cannot start the full ending until the first one is behind you. The first ending has its own set of requirements, and clearing them opens the path forward.
Clear the seven purple puzzles and any you missed
After the first ending plays out, seven purple puzzles unlock. These are harder versions of challenges you have already faced during the game, and they can take real time if the earlier puzzles gave you trouble.
The purple puzzles are not the only thing left. Any puzzles you skipped or missed earlier in your playthrough also come due now. The full ending requires every single puzzle to be completed, with no exceptions.
Once every puzzle is done, the final key appears as your reward. It rises up from the ground, and this is the last piece you need to reach the true ending.
Enter the secret room to trigger the true ending
With the final key collected, head back to the spawn area and look for the secret room. It is tucked between the broken black sphere on the wall. Without the final key, you cannot get inside.
Inside the room, read the messages. Doing so triggers the true ending sequence, the payoff for all the extra work after the game seemed finished.
How to confirm the Big Game trophy unlocked
The Big Game trophy pops alongside the true ending. It is tied directly to 100% completion, so if it has not unlocked, one of the requirements is still outstanding. Run through the checklist below and the trophy will follow.
- Every puzzle in the game is complete, including all seven purple puzzles.
- No puzzles from your earlier playthrough are left unsolved.
- The final key has risen from the ground and been collected.
- The secret room near spawn has been entered and its messages read.
- The true ending sequence has played out.
If the trophy still has not appeared, the most common reason is a missed puzzle somewhere in the world. The final key will not spawn until the count is truly at 100%, so backtrack and look for any challenge you passed over. On PlayStation, Big Game is also one of the last pieces you need for the Big Trophy platinum, which requires unlocking every other trophy in the game.
