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.
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 have a teammate paint one body section gold, silver or bronze |
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 backpack's exact spot is in the beginner FAQ.
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.
