Big Walk walkthrough: a route through the towers

The Big Walk walkthrough follows a repeating task: solve cooperative puzzles, carry their red rewards to a tower, then finish the released key’s route. The Red Tower gives your group a map; later towers open transport, and the Black Tower leads toward the ending. ^{[destructoid-route]}

Start with one host and a shared save

Choose the person who will keep hosting future sessions. Progress belongs to the host, and the rest of the group disconnects when that host ends the session. Start a world configured for the minimum number of players who will remain available. ^[faq]

In the opening area, practice picking things up, gesturing and communicating through the puzzle structures. Finish its four reward challenges to open the drawbridge and reach the main island. ^{[destructoid-route]}

Pick the next unlock

Progression stop	What it gives you	Where to go for help
Red Tower	Map Room access	Map unlock
Green Tower	Chairlift transport	Use the high viewpoints to orient the group
Yellow Tower	Tunnel access	Also opens the route to metallic paint
Blue Tower	Moving trains	Train unlock and controls
Black Tower	Key to the Wall	Black Tower checkpoint

This is a navigation plan, not a requirement to complete every side puzzle in exactly this order. Transport makes later trips easier. A finished reward does not have to remain beside the puzzle that produced it. Carry it to the tower you are working on and check that it has been accepted. ^{[destructoid-route]}

Finish each key route

After filling a tower’s receptacles, take the released key to its first cutter and follow the directional markers. Keep passing it through the indicated stations until it fits the final mechanism. A key in your hands is an intermediate step, not confirmation that a transport system is unlocked. ^{[polygon-train]}

If a distant number puzzle stops you early, mark it and return with the paper map. The 4166, 1899 solution requires the group to split between the reward container and a remote button. ^{[gs-coordinates]}

After the last tower

Use the Black Key at the Wall, then continue to the sphere for the final main sequence. Expect communication restrictions to become part of the challenge. For the full spoiler route, open Big Walk endings. ^{[polygon-ending]}

If a challenge is inaccessible to someone in the group, the host can enable challenge skipping through the accessibility menu when starting a session. You can pause the adventure and return to the same host’s save later. ^[faq]
