Progressive puzzle hints

Open only the layer you actually need.

Stand where the red tower and rail line are visible together. Compare them with the current road before moving.

Use a route that can return to the previous landmark, then handle the second signal from the fork. Keep one teammate at the return point.

Finish the observation around the red tower, use the train direction to confirm the tunnel entrance, and regroup at the last shared landmark if the party splits.
