Big Walk has 12 achievements on Steam and the same 12 as trophies on PS5 — PlayStation players also get a Platinum for earning them all, fittingly named Big Trophy (per All Things How's full list). Most unlock naturally as you explore, but a few ask for deliberate effort. Here's the full list and how to approach it.
Progression trophies
These come from the island's main milestones — each of the colored towers unlocks one of the island's systems, and the trophies follow that path.
| Trophy | How to unlock |
|---|---|
| Big Walk | Cross the drawbridge — earned by clearing the four starting-area puzzles and lowering the big red bridge |
| Big View | Visit the map — the red tower unlocks the map room; see the map guide |
| Big Tunnel | Enter a big tunnel — the yellow tower opens the tunnel network |
| Big Ride | Ride the train — the blue tower starts the railway; see the train puzzle guide |
| Big Sit | Ride the chairlift — unlocked through the green tower |
| Big Goodbye | Finish the game — reach the credits |
| Big Game | Completely finish the game — the full ending, separate from Big Goodbye; see the ending guide |
Note the distinction at the end: Big Goodbye is for reaching the credits, while Big Game requires the complete ending — 100% completion including the post-game purple remix puzzles. Use the 100% completion guide for a run-order checklist.
Puzzle rewards are not themselves trophies. The red prizes that puzzles hand out are progression items — collecting them helps a group reach deeper parts of the island — but they are not directly tied to a specific achievement or trophy. Five of them placed on the red tower's roof unlock the map room and the Big View trophy (see the map guide). The game does not publish an official name or total for these rewards: “nubbins” and “gourd” are informal player nicknames, not official collectible labels.
Extra-effort trophies
| Trophy | How to unlock |
|---|---|
| Big Climb | Reach the island's highest point — take the green tower's chairlift up, then walk the rest of the way to the summit (per TheGamer's trophy guide) |
| Big Makeover | "Get shiny" — find the metallic paint hidden in a secret salon inside the tunnel network (you'll need the yellow tower's tunnels first), then follow the Big Makeover route and have a teammate paint one body section |
These two are the ones to plan around: don't leave them for post-game cleanup — work them into the middle of your playthrough, when your group is already crisscrossing the island for towers and prizes.
Gear-finds
| Trophy | How to unlock |
|---|---|
| Big Help | Wear something on your hip — hip items like walkie-talkie belts are found in the island's blue circular buildings |
| Big Pack | Wear a backpack — also found in blue circular buildings; the easiest one to reach sits near the red tower |
Both come from wearable items found in the world, and there's a co-op twist: according to Game Rant and Insider Gaming, you can't put these items on yourself — a teammate has to equip them on you. The easiest blue-building route is in the backpack location guide.
The twelfth trophy: Big Wall
The twelfth and final achievement is Big Wall — "Go beyond the wall." It's the game's most demanding trophy, confirmed by TheGamer, Insider Gaming and All Things How.
It's a late-game unlock tied to the black tower: once your group has finished the colored-tower key sets, the black tower opens. All Things How's walkthrough describes delivering its puzzle rewards to receive a final key, which opens the gate in the wall at the far west of the island — the trophy pops when your character physically steps through to the other side. Details of that final sequence (with spoiler warnings) are in the ending guide.
To be confirmed: The exact number of puzzle rewards the black tower requires before it hands over its key — currently single-sourced. The trophy itself and its "go beyond the wall" condition are solidly confirmed.
Platinum roadmap (PS5)
- Play naturally through the starting area — clear the four starting puzzles, lower the drawbridge (Big Walk) and grab the gear trophies (Big Help, Big Pack) as the blue buildings turn up.
- Mid-playthrough: clear the colored towers — Big View (map), Big Tunnel (tunnels), Big Ride (train), Big Sit (chairlift) — and pick up Big Climb and Big Makeover while you're exploring, not after.
- Finish the black tower, cross the wall (Big Wall) and reach the credits (Big Goodbye).
- Post-game: complete the seven purple remix puzzles and everything else for the full ending (Big Game) — and the Big Trophy Platinum pops.
On Steam the same list appears as 12 achievements, minus the Platinum.
What the latest Big Game reports add
Recent completion reports say the purple rewards come from post-game remix puzzles and are placed in a separate room with the red rewards that the tower route did not need. Filling that room is reported to produce the final key used on the hidden-ending route, while the normal credits run can still skip puzzles.
This gives the 100% route a practical target: mark every purple reward and every skipped red reward before returning to the tutorial-area black sphere. The official FAQ confirms that Big Walk has a hand-crafted ending, but it does not publish the community room count.
To be confirmed: Community reports converge on 15 slots, but the split is not official: one early report says six purple rewards, while later full-completion reports say seven purple plus eight skipped red rewards. Keep that split To be confirmed.
