This Big Walk trophy guide covers the 13 trophies listed for the PS5 version: one platinum, ten gold, and two silver. Two requirements are secret, so the completion route below separates visible milestones from ending spoilers.
Confirmed traversal and equipment trophies
Big Walk is awarded for crossing the drawbridge. Big View requires visiting the map, Big Sit requires riding the chairlift, Big Ride requires riding the train, Big Tunnel requires entering a big tunnel, and Big Wall requires going beyond the wall.
Big Pack is earned by wearing a backpack, while Big Help requires wearing something on your hip. Big Climb asks the group to reach the highest point. These are specific interaction milestones rather than a requirement to solve every puzzle immediately.
Appearance and completion trophies
Big Makeover carries the requirement “Get shiny.” It is tied to a late-game appearance interaction and needs another player to apply the relevant finish, consistent with the game's cooperative character-painting system.
The two secret trophies are Big Goodbye for finishing the game and Big Game for completely finishing the game. The distinction confirms that the normal ending and full completion are separate objectives.
Plan the platinum efficiently
Keep one host world for the whole group because the official FAQ says progress saves automatically to the host. Complete the main route first, use the newly opened transport and map tools to clean up traversal milestones, then finish the optional puzzle route for Big Game.
Big Trophy unlocks after every other trophy. The list does not require a separate difficulty mode or solo run, and the official game itself has no single-player mode; all meaningful progression is designed for cooperative multiplayer.
