Quick answer: Tunnels are convenient shortcuts once your group can consistently identify each entrance and exit.
What to do
Record every entrance with a surface landmark; stop at junctions; make sure everyone knows which exit is planned.
Helpful checks
Treat an unfamiliar tunnel as a new route, not as a fast-travel shortcut, until the whole group has mapped it.
Frequently asked questions
Is this official information?
Multiplayer, saves, joining, communication and troubleshooting facts are checked against the official Big Walk FAQ. Route notes are fan-made and should be rechecked after updates.
What if our group is still stuck?
Regroup at a known landmark, confirm the host and session state, then work through one check at a time rather than changing several things at once.
