The first ending in Big Walk feels like a natural stopping point, but the game isn't finished with you yet. A second, true ending sits locked behind everything the game has to offer, and earning it means going back to solve every puzzle you skipped the first time around.
How many endings does Big Walk have?
Big Walk has exactly two endings. The first arrives once you've worked through the colored towers, unlocked the black tower, and collected the required puzzle rewards. That key opens the wall, and from there you travel to the large black sphere in the distance. Reaching it triggers a set of final puzzles, and clearing those delivers the initial ending.
Most players will hit that moment and assume the credits mean they're done. They're not.
What do you need to do to unlock the true ending?
The true ending, paired with the Big Game achievement and full 100% completion, requires clearing every single puzzle in the game. That includes any puzzles you bypassed during your first run, plus a set of seven purple puzzles that only become available after the initial ending plays out.
These purple puzzles are harder versions of challenges you've already seen, so you'll recognize the mechanics even if the difficulty has a sharper edge. Work through all of them, collect the final rewards, and you'll receive a final key.
With that key in hand, head to the secret room near the spawn area. It sits between the broken black sphere on the wall. Enter it, and the second ending triggers.
Big Walk Guide: How to Unlock the Full Ending
How to Unlock the Big Game achievement
Here's the full sequence to reach 100% completion and unlock the Big Game achievement:
- Complete all colored towers during your main playthrough.
- Unlock the black tower and collect the required puzzle rewards.
- Use the key to open the wall and travel to the large black sphere.
- Clear the puzzles at the black sphere to trigger the first ending.
- Return and complete any puzzles you missed earlier in the game.
- Complete all seven purple puzzles that unlock post-credits.
- Collect the final rewards and the final key.
- Travel to the secret room near the spawn area, located between the broken black sphere on the wall.
- Enter the room to trigger the true ending and earn Big Game.
How hard are the purple puzzles compared to the main game?
The purple puzzles pull from mechanics you've already encountered, so there's no brand-new system to learn. The difficulty increase is real, though. Expect the same core logic pushed to a more demanding level. After testing all seven against fresh eyes, the biggest challenge isn't any single puzzle type, it's the cumulative pressure of needing to clear all of them cleanly without a shortcut.
If you've been playing in a group, this section rewards coordination. For context on how multiplayer works in Big Walk, the guide on player count and co-op setup covers what group size gives you the best shot at these harder challenges.
What else should you track on the way to 100%?
The path to the true ending overlaps heavily with the rest of the game's achievement list. If you're committing to full completion anyway, it's worth handling other collectible and item-based achievements at the same time. The Big Walk trophy and achievement list breaks down all 12 trophies, including which ones require deliberate effort versus which pop naturally through normal play.
For everything else the game has to offer, the full Big Walk guides collection covers maps, items, and puzzle locations in detail.
