Chapter 13: As One walkthrough

The critical path

Follow Ariadne's illuminated cables, move between safe light zones and clear Petrified rooms on the road to the finale.

Follow these Chapter 13 checkpoints in order; each one marks a progression action or a search window before the next one-way transition.

• Follow Ariadne's temporary cables through the circular platforms and use each fixed light as the next safe checkpoint.
• In the labyrinth, keep moving toward the beam and use grapnel swings to end repeated creature pursuits.
• After the third escape, take the left stairway from the light to recover the Labyrinth Plan before proceeding.
• In Petrified rooms, activate the corner light first and sweep it across enemies and growths before touching the reflector.
• Near the final beam, check the side path immediately after the last squeeze-through gap for the Poisoned Syringe.

Chapter checklist

Before the final one-way transition, check the chapter tracker for 0 Blades, 2 Artefacts and 1 Charm.

After activating a light, use it both as shelter and as a tool to destroy the growths hiding paths and pickups.

If the puzzle stops you

Chapter 13 uses the sphere, environmental markings or light routing at the blockers noted above. Reveal the full mechanism first, then change one pedestal, reflector or beam at a time so the failed link remains visible.

The dedicated puzzle guide places Chapter 13's verified solution in chronological order and preserves the surrounding objective name, making it easier to confirm that you are solving the same room.
