Big Walk 100% Completion Guide
A reliable completion run separates the credits route from cleanup instead of forcing every optional challenge into the first session.
Direct answer
Earn the 12 Steam achievements and finish remaining puzzle work
Steam publicly lists 12 achievement names and exposes conditions for ten of them. Complete the named travel, gear, high-point, shiny and wall objectives, then use the community-documented credits and post-game cleanup route for the hidden-condition Big Goodbye and Big Game achievements.
Before you start
- Choose a dependable host and keep a shared progress note.
- Record any challenge skipped through accessibility settings.
- Do not rely on an unverified collectible or reward total.
Step-by-step
- 1
Complete the route achievements
Lower the drawbridge, visit the map, enter a big tunnel, ride a train and ride the chairlift.
- 2
Collect the side objectives
Wear a backpack, wear a hip item, reach the highest point and have a teammate apply metallic paint.
- 3
Finish the story route
Go beyond the wall for the Steam-verified Big Wall condition, then follow the community-documented credits route.
- 4
Audit skipped puzzles
Compare the shared note and Map Room with every route page, then finish challenges skipped on the first pass.
- 5
Complete post-game work
Track every visible purple remix and its reward without assuming a disputed count.
- 6
Test the community completion route
Return to the reported full-completion route only after the host world shows no known unfinished puzzle work.
Still stuck?
- If one achievement is missing, verify its exact Steam description before repeating unrelated content.
- If a gear objective was earned by one guest, equip the item separately on each player who needs it.
- If Big Game remains locked, recheck skipped base puzzles and staged post-game rewards before replaying the end sequence.
Spoiler and verification boundary
What is verified on this page
This page reveals story milestones and full-completion structure but not the final secret scene.
All 12 achievement names and ten public conditions are verified on Steam. Big Goodbye and Big Game have hidden conditions there, so their credits and cleanup routes remain community-sourced; disputed reward totals are omitted.
