Big Walk true ending: unlock Big Game

Big Goodbye and Big Game are sequential endings

The two hidden achievements are not branches and there is no choice that locks one out. Big Goodbye is the normal campaign ending. Big Game is the 100% finish that becomes available after Big Goodbye on the same save.

This distinction matters because the credits look final. The official FAQ confirms Big Walk has a defined ending, while Steam lists two hidden completion achievements. Player reports consistently describe the second as the island-wide cleanup route.

Finish Big Goodbye first

Complete the coloured tower progression, continue through the Black Tower and beyond the wall, then clear the cooperative rooms inside the large black sphere. Follow the opened route through the final exit to trigger Big Goodbye and the credits.

Do not start a new world after the credits. The host owns all progress, so the same person must reopen the completed save for the post-game state to appear. Other players can leave and return, but changing hosts means changing worlds.

What changes after the credits

Reloading the completed host save exposes the remaining completion route. The purple challenge set becomes part of the active map, unfinished normal puzzles still count, and the final collection structure can be completed.

Open the Map Room before the group starts walking. A blue flag marks a completed puzzle, while a reward lying sideways shows a solved challenge whose reward was never delivered. That model is more reliable than anyone’s memory of the first playthrough.

Clear every normal puzzle the group skipped

The main route does not consume every normal challenge on the island. A group can reach Big Goodbye while optional red rewards remain untouched or undelivered. Those leftovers are part of the 100% requirement.

Work by map cluster rather than by remembered puzzle name. Clear every unfinished marker and deliver every sideways reward before assuming a purple puzzle failed to count.

Complete all seven purple challenges

The seven purple puzzles are harder remixes around the far chairlift ridge. They include long transport, silent communication, drawing and timed movement variants. Each one produces a purple reward for the final hand-in.

They can be reached unusually early through terrain routes, but the clean completion order is to finish Big Goodbye first, reload the same save and clear the seven while the updated Map Room records each state change.

Deliver the final 15 rewards

Community completion reports describe the last collection as fifteen remaining rewards: seven purple rewards from the post-game set and eight red rewards from normal puzzles not consumed by the main route.

Carry them to the green completion structure near the tutorial and Map Room side of the island. Fill every slot. When the set is complete, the structure produces the white key used for the final hidden route.

Use the white key near where the walk began

Return toward the starting tutorial area. The small black sphere there has opened into a key route after the first ending. Insert the white key, descend into the hidden sequence and complete the instructions inside to trigger Big Game.

Bring every player who needs the achievement into the session before finishing. Early reports disagree about some platform-specific trophy behaviour, so the safest approach is to have the full group present for the final sequence.

If Big Game or the true ending is not unlocking

Do not replay the final room first. Audit the host save from the Map Room and check the final structure before assuming the achievement is bugged.

• Confirm Big Goodbye already unlocked on this host save.
• Check every normal map marker, including solved rewards still lying sideways.
• Confirm all seven purple challenge markers changed state.
• Count all fifteen filled slots at the green completion structure.
• Make sure the white key was used at the small sphere near the starting area, not the large endgame sphere.
