Big Walk is built around exploration, communication, and cooperative puzzle-solving rather than traditional combat. That also applies to its achievement list: most achievements are awarded naturally as you explore the island, use its transportation systems, discover equipment, and progress through the world. The real challenge comes at the end if you want the final hidden achievement and the complete trophy collection.

The complete trophy list contains 13 trophies: one Platinum, 10 Gold and two Silver, with two of the trophies marked as secret.
Big Goodbye is the first of Big Walk’s two hidden achievements.
Its secret description is simply “Finish the game.” That means you don’t need to complete every puzzle or find every optional collectible for this achievement. You need to complete the main game and reach its normal ending.
How to reach the normal ending
- Continue through the main progression and solve the required puzzles that open up new areas and routes.
- Work through the island’s major progression structures and follow the path toward the game’s later areas.
- Eventually, you’ll reach the point where you can progress beyond the wall. This also gives you the Big Wall achievement if you haven’t already earned it.
- Continue through the remaining main-game objectives until the ending sequence begins.
- Finish the ending sequence to unlock Big Goodbye.
- You can safely treat this as the game’s normal completion trophy. You don’t have to stop and hunt down every optional puzzle before finishing the story.
This is the achievement that matters if you’re trying to get 100% completion.
Big Game is described as “Completely finish the game,” and current player reports indicate that this goes substantially beyond simply reaching the normal ending.
After completing the main game, additional content becomes available, including purple puzzles. These are important because their rewards contribute toward the requirements for the game’s true completion.
Recent player reports indicate that there are seven purple puzzle rewards, alongside eight additional red rewards, making 15 total pieces needed for the post-game completion objective.
How to complete the post-game requirements of Big Walk
- Finish the main game first and unlock the normal ending.
This is important because the additional content required for Big Game becomes available after completing the main progression. - Return to the island and look for the newly available purple puzzles.
These puzzles are separate from simply completing the main storyline. They represent part of the game’s post-game completion challenge. - Complete all seven purple puzzles.
Each completed purple puzzle provides one of the purple pieces needed for the final collection. - Find the remaining eight red pieces from the additional challenges that count toward the final requirement.
The full post-game requirement is 15 pieces: seven purple and eight red. - Take all 15 pieces to the green structure near the map room.
This is the structure that players have identified as requiring the complete collection of seven purple pieces and eight additional red pieces. - Use the completed collection to obtain the key required for the final hidden sequence.
- Return to the relevant location from the opening/tutorial portion of the game and use the key to access the final hidden area.
- Complete the resulting final sequence.
Doing this is what current player reports identify as the route to the game’s hidden/true ending, and completing all of the associated challenges is what ultimately unlocks Big Game.
Why Big Game takes longer than Big Goodbye
The distinction between the two secret achievements is important.
Big Goodbye is essentially your main-game completion trophy. You can finish the game’s central journey, see the normal ending, and receive it without fully clearing the island.
Big Game is the true completion trophy. Players pursuing the Platinum have reported needing to return after the main ending and complete the additional puzzle content rather than simply stopping after the credits.
This explains why you might finish the story and still have one achievement missing. If your trophy list shows everything except Big Game and the Platinum, you haven’t necessarily missed a secret trigger. You most likely still have the post-game challenges to complete.
Recent players who have reached 100% specifically describe completing all the purple puzzles and the remaining required challenges, with one player reporting that the full completion requires going beyond the normal game and exploring areas that are easy to overlook.
Can you miss any Big Walk achievements?
The good news is that the achievements are not considered missable according to current player reports.
A player who completed the Platinum reported that there was nothing missable, meaning you can finish the main game and return to clean up achievements afterward.
That makes the best approach fairly relaxed. You don’t need to constantly stop your group and worry about whether you’ve just passed an irreversible achievement opportunity. Enjoy the island, solve the puzzles, use the transportation systems when you encounter them, and return for cleanup afterward.
This is especially useful for Big Game because trying to hunt down every optional puzzle while you’re still learning the island can make the first playthrough unnecessarily complicated.
How long does it take to 100% Big Walk?
The exact time varies considerably depending on how quickly your group solves puzzles and how much time you spend exploring. Recent players have reported roughly 15–18 hours for a full completion, although that isn’t a fixed requirement and experienced groups can potentially move faster.
The main game itself is considerably shorter than a full completion run. The extra time comes from tracking down optional puzzles and completing the post-game content required for Big Game.
Because Big Walk is designed specifically around cooperative communication, having a group that communicates effectively can make a noticeable difference. The game supports 2–12 players, and its puzzles are designed around players sharing information and working together.
If you’re playing casually, focus on reaching the normal ending first and enjoy the journey with your group. If you’re chasing 100%, use the post-game period to methodically clear the additional puzzles and collect the required pieces. Current player reports confirm that the extra work is manageable and that the Platinum is not considered particularly difficult, although the additional puzzles can make the completion run substantially longer.
