Big Walk Trophy Roadmap
Use one consistent host from the opening area through the post-game route because the host owns progression. Most achievements follow the main sequence naturally, but several require a specific interaction after a facility opens. Perform those interactions when each facility becomes available so they are not forgotten.
The gameplay list contains 12 named achievements. On PS5, Big Trophy is the additional Platinum trophy and unlocks after the other trophies; it is not a separate gameplay objective.
During the first run, lower the drawbridge, complete the four colored towers, open the Black Obelisk route, pass the western wall, and finish the Sphere. Along the way, equip wearable bags, visit the tunnel salon, and climb the highest chairlift structure if the group wants to reduce cleanup. Big Goodbye marks the first ending.
After the credits sequence, reload the same save rather than starting again. Complete any skipped island puzzles and the seven harder purple challenges, collect the remaining rewards, and obtain the white key. Using it in the tutorial-area secret route leads to Big Game.
Main Story Achievements
- Big Walk
- Lower and step onto the opening drawbridge
- Big Wall
- Use the Black Key and continue beyond the western wall
- Big Goodbye
- Complete the Sphere and pass through the final exit
- Big Game
- Finish the full-completion route and additional ending
Big Walk follows the tutorial progression. Collect the four starting puzzle rewards, release and prepare the first key, then use it on the red drawbridge. Step onto the lowered bridge to trigger the achievement.
Big Wall comes later, after the colored tower routes make the Black Obelisk available. Bring six puzzle rewards to it, take the Black Key to the far-west wall gate, and continue beyond the wall. The path ahead leads toward the giant Sphere.
Big Goodbye is the normal ending achievement. Complete the puzzles inside the Sphere, leave through the far side, and follow the final route through the turnstile and white door. Big Game is a separate post-game completion objective covered below.
Easy-to-Overlook Facility Achievements
The colored tower keys open major facilities, but the achievement condition may require entering or using the result. Do the final interaction immediately after each unlock so it is not forgotten. All four can still be cleaned up before finishing the save.
Big View
Complete the Red Tower route, prepare its key, and open the Map Room beside the tutorial route. Enter or visit the Map Room after the door opens.
Big Sit
Complete the Green Tower route and use its key at the nearby chairlift station. Sit on a moving chair after the system begins running.
Big Tunnel
Complete the Yellow Tower route and unlock the Yellow Door. Enter the newly available tunnel system instead of leaving immediately.
Big Ride
Complete the Blue Tower route and activate the trains at the mountainside station. Step onto a moving train to satisfy the documented trigger.
Equipment, Climb, and Makeover Achievements
Blue spiral or basket-shaped pavilions contain wearable backpacks and hip bags or belts. For Big Pack, another player must place a backpack onto your character. Big Help follows the same cooperative interaction with the waist-worn item.
For Big Climb, start from the station that activates the chairlift and ride one station west to the island’s highest stop. Leave the chair and climb all the way to the top of the visible structure or sphere; no additional puzzle is required at the summit.
Big Makeover requires access to the tunnel system. Find the salon near the Red and Blue tunnel connection, around the rave area, then cross the green bridge and descend the red stairs into the purple salon space. Select one of the three lower shiny colors and have another player paint your character.
How to Unlock Big Game
Big Game cannot trigger before Big Goodbye. Finish the normal ending first, then reload the same saved world rather than starting again. Continue from that world to complete the remaining route.
Clear every puzzle that the group skipped and complete the seven purple-reward challenges in the southern region. These are harder variations of earlier timer, golf, button-location, speaker, posing, obstacle-course, and symbol-sign puzzles. The completion sources listed below require all seven as well as unfinished standard puzzles.
Bring the final eight red rewards and seven purple rewards to the separate green completion building near the Tutorial/Map Room area and red train line. It is not the Green Tower: look for the building with 15 empty slots. Filling all 15 produces the White Key.
Return to the initial tutorial area and find the small black sphere split open around a key slot. Insert the White Key, go downstairs into the hidden route, and remain through the final sequence. Walk through the bright white opening when it appears to register the completion ending and Big Game.
Frequently Asked Questions
Can you earn Big Goodbye and Big Game on one save?
Yes. Complete Big Goodbye first, then reload the same host save rather than starting a new world. Finish the remaining puzzles and completion route to earn Big Game.
Which Big Walk achievements are easy to overlook?
After each facility unlock, enter the Map Room for Big View, sit on a moving chairlift for Big Sit, enter the tunnel network for Big Tunnel, and board a moving train for Big Ride.
How do you unlock Big Pack and Big Help?
Find wearable bags in the blue basket-shaped pavilions around the island. Another player must pick up and attach the item to your character: use a backpack for Big Pack and a hip bag or belt for Big Help. Equipping the item yourself does not satisfy the documented cooperative action.
What unlocks the Big Game trophy?
After Big Goodbye, finish the remaining standard puzzles and seven purple challenges. Put the final eight red and seven purple rewards into the 15-slot green building near the Tutorial/Map Room area, then use its White Key in the split black sphere at the starting area.
