Find the route without copying a wrong coordinate
The live description confirms that players can find a hidden tunnel and escape together on Easy, Normal or Hard. Room layouts and the tunnel entrance can change, so a screenshot from another server is not a permanent map.
- Scout the cell and the first reachable room before spending all your rubble on upgrades.
- Mark dead ends, guard pressure and any interactable wall or floor detail.
- Choose Easy for the first route record, then repeat the same search on Normal or Hard.
- Keep a teammate on the return path while another player checks suspicious openings.
- Write the current difficulty, chapter, server date and escape time beside the result.
What counts as a useful guide update
A durable tunnel guide needs the chapter and difficulty, not only a coordinate. EarlyWiki will add a location diagram after a current run reproduces it; until then, the official experience remains the authority for the live route.
