The list focuses almost entirely on progressing through the island, unlocking its major traversal systems, finding useful equipment, reaching important locations, finishing the story, and then completing the remaining post-game content.
1. Big Walk Trophy & Achievement Structure
Big Walk has a small trophy list, but earning the Platinum requires completing most of the game’s main progression and post-game content. The world adapts depending on whether the host selects a two-player, three-player, or four-plus-player version, so the Platinum can be completed with only two people.
Keep the same host throughout the run whenever possible. The host owns the save file and all world progress, and that player must host again when the group returns for another session. Crossplay works between supported platforms, but there is no automatic online matchmaking.
- PlayStation: 13 trophies, including Platinum.
- PC / Steam: Steam Achievements are supported.
- Trophy breakdown: 1 Platinum, 10 Gold, and 2 Silver.
- Secret trophies: Two.
- Online requirements: Yes.
- Co-op requirements: Yes. Minimum two players, maximum 12.
- Crossplay: Available.
- Difficulty requirement: None tied to the trophy list.
- Missable trophies: None identified. The world can still be revisited after reaching the ending.
- Minimum playthroughs: One co-op world, followed by post-game cleanup.
2. All Trophies & Achievements List
The full list is much smaller than most adventure games. Several trophies unlock naturally while progressing through the main towers and gaining access to the drawbridge, map, chairlift, train, tunnels, and areas beyond the wall.
The remaining trophies involve wearing specific equipment, reaching the island’s highest point, getting shiny, finishing the game, and completing everything required for the post-game Big Game trophy.
Big Goodbye and Big Game are the two secret Gold trophies, so their descriptions reveal that the main ending is not the final requirement for the Platinum.
| Trophy / Achievement | Requirement |
|---|---|
| Big Trophy | Unlock every other trophy. |
| Big Walk | Cross the drawbridge. |
| Big View | Visit the map. |
| Big Sit | Ride the chairlift. |
| Big Ride | Ride the train. |
| Big Tunnel | Enter a big tunnel. |
| Big Wall | Go beyond the wall. |
| Big Pack | Wear a backpack. |
| Big Help | Wear something on your hip. |
| Big Climb | Reach the highest point. |
| Big Makeover | Get shiny. |
| Big Goodbye | Finish the game. |
| Big Game | Completely finish the game. |
3. Best Platinum Trophy Strategy
The easiest way to earn the Big Walk Platinum is to complete the main story first, grab simple trophies along the way, and leave post-game cleanup until the end.
- Start a co-op world with at least two players. Keep the same host, as the host owns the save progress.
- Complete the main towers. Start with the Beach Tower, then progress through the Red, Blue, Green, and Yellow Towers while using the map, train, chairlift, tunnels, and drawbridge.
- Grab optional trophies while exploring. Wear a backpack, equip a hip item, reach the highest point, and complete the shiny transformation.
- Go beyond the wall and finish the story. This unlocks Big Wall and Big Goodbye.
- Complete the post-game content. Collect the remaining purple and red progression items and place them at the green structure near the Map Room to unlock Big Game.
- Finish any remaining trophies. Once everything else is complete, Big Trophy unlocks the Platinum.
