Black Tower guide and vision trigger

Fact-checked Aug 11, 2026Multiple independent completion reports; no official walkthrough

Quick answer: Finish the four coloured tower routes, complete the Black Tower panel, then gather your group at the entrance buttons. It is normal for only one player to receive the vision.

Reach the Black Tower phase

Independent completion reports consistently place the Black Tower after the Red, Green, Blue and Yellow tower routes. Finish those four coloured systems before treating the Black Tower as the group’s next progression target.

Fill the visible Black Tower panel

Bring control-panel rewards from completed island puzzles and place them into the open slots shown at the tower.

Open the door together

Bring the party to the entrance and coordinate the door buttons. Multiple groups report that the player who presses the final required button receives the vision while companions remain outside it.

  • Only one player seeing the vision has been reported consistently
  • Other players may see the affected character become rigid with spiral eyes
  • Use the radio or proximity voice to compare what each side sees

What happens after the Black Tower

Completing the Black Tower advances the group toward Big Walk’s main ending. Player accounts describe a final gate, a long shared walk toward the large sphere, and a later sequence where normal group communication changes.

The separate completion route

The main ending does not require every purple puzzle. After finishing it, completionist groups can return to the island, solve the harder purple challenges and use the later structure near the Map Room to progress toward the additional ending route.
