Quick answerThe Blue Tower cluster leads to the Trains unlock. Its guide should pair every pattern or part requirement with a clear visual reference.
Blue Tower route
- Locate the entrance and gather the group.
- Work through patterns and required parts in order.
- Use the key cutters and confirm Trains are active.
Avoid common confusion
- Use screenshots for visual patterns instead of ambiguous color names.
- Assign one player to call the sequence.
- Check that every player sees the same completed state.
Next step
- Add train destinations to the map guide and link any required item pages.
