Spoiler note
Several completion goals are intentionally hidden or secret on Steam. The PlayStation list also adds a platinum trophy, so this page keeps the platform split visible instead of flattening both versions into one list.
Use the table headings before the full objective if you want to avoid late-game spoilers.
Steam achievements
Steam lists 12 achievements. Two of them are hidden on the store page, but the goal names are still useful for planning a clean save or a spoiler-safe checklist.
| Achievement | How to unlock | Visibility |
|---|---|---|
| Big Walk | Cross the drawbridge | Visible |
| Big Pack | Wear a backpack | Visible |
| Big View | Visit the map | Visible |
| Big Help | Wear something on your hip | Visible |
| Big Sit | Ride the chairlift | Visible |
| Big Climb | Reach the highest point | Visible |
| Big Ride | Ride the train | Visible |
| Big Tunnel | Enter a big tunnel | Visible |
| Big Wall | Go beyond the wall | Visible |
| Big Goodbye | Finish the game | Hidden on Steam |
| Big Game | Completely finish the game | Hidden on Steam |
| Big Makeover | Get shiny | Visible |
PlayStation trophy list
The PlayStation list tracked by Gamer Social Club and TrueTrophies has 13 trophies total: 2 silver, 10 gold and 1 platinum. The platinum trophy, Big Trophy, is the wrapper for the full set.
The objective list mostly mirrors Steam, but the PlayStation presentation makes the hierarchy clearer for completionists who are tracking rarity as well as objective names.
| Trophy | Rarity | Description |
|---|---|---|
| Big Trophy | Platinum | Unlock every other trophy. |
| Big Walk | Gold | Cross the drawbridge. |
| Big Pack | Silver | Wear a backpack. |
| Big View | Gold | Visit the map. |
| Big Help | Silver | Wear something on your hip. |
| Big Sit | Gold | Ride the chairlift. |
| Big Climb | Gold | Reach the highest point. |
| Big Ride | Gold | Ride the train. |
| Big Tunnel | Gold | Enter a big tunnel. |
| Big Wall | Gold | Go beyond the wall. |
| Big Goodbye | Gold | Finish the game. |
| Big Game | Gold | Completely finish the game. |
| Big Makeover | Gold | Get shiny. |
Completion notes
If you are building your own checklist, record the platform next to each unlock. The Steam and PlayStation lists are close, but the rarity and wrapper trophies are not identical.
For this wiki, hidden objectives stay spoiler-tagged in summaries and are only expanded when a reader deliberately opens the full list.
Big View: map route detail
The Big View objective is listed as visiting the map. Insider Gaming's route report says the map becomes available after the Red Tower objectives are completed, the received key is cut through the successive cutters and the nearby blue tunnel is opened. That room contains both the large island map and a portable paper map.
The achievement objective is cross-checked against the platform lists; the key-cutting sequence and the two-map explanation remain credited guide details until this wiki records an in-game capture.
| Step | What to check | Status |
|---|---|---|
| Red Tower | Place the required puzzle rewards and receive the key | Route reported by Insider Gaming; platform objective cross-checked |
| Key cutters | Follow the successive cutter markers | Third-party route; pending in-game capture |
| Blue tunnel room | Open the room and visit the map | Third-party route; achievement name confirmed |
Third-party full-ending report (not independently verified)
Games.GG published an Aug 4, 2026 guide claiming that Big Walk has an initial ending followed by a completion route involving missed puzzles, seven purple post-credits challenges and a final key. It places the reported final-room trigger near the starting area and connects the route to the Big Game achievement.
The official FAQ confirms that Big Walk has a beginning, middle and end, but does not confirm two endings or the purple-challenge route. The platform achievement pages confirm the Big Game achievement name, not the route described by Games.GG. Keep this as a spoiler-marked lead until the route is reproduced in-game and tied to a platform capture.
| Reported step | Status on this wiki |
|---|---|
| Complete the main colored-tower route and reach the first ending | Games.GG report; route not independently reproduced here. |
| Return for skipped puzzles and seven purple challenges | Games.GG report; do not present as official until verified. |
| Collect a final key and enter the reported secret room near spawn | Games.GG report; location and trigger require in-game capture. |
| Unlock Big Game / complete the game | Achievement name is confirmed by Steam and PlayStation sources; route remains separate. |
