CONTROL Resonant Power Lines — Tuning Fork & Vanished Station
Quick answer: CONTROL Resonant Power Lines is a Central subway story quest (after Arish’s Briefing): reroute power via Calibration Units + Tuning Devices across stations. The hard puzzle is Vanished Station Platform A & B — Mold bridges broken cables on B. Extended Rush helps while ferrying the charge.
Stations overview
You calibrate multiple subway nodes (Perimeter, East Park, Vanished, etc.). Each site: place Calibration Units on yellow squares, then activate the Tuning Device. Notes on-site tell which squares count.
Vanished Station — Platform A
- Collect four Calibration Units total (two per platform).
- Open the gate between A and B so you can walk both sides.
- On Platform A: clear Mold covering yellow tape if a powered generator grows it, place two units on the marked squares, activate A’s Tuning Device.
Vanished Station — Platform B (Mold bridge)
- Broken floor cables need Mold to conduct — grow Mold across the gap by moving the electrical charge between Platform B power cores.
- Keep Mold that bridges the wires; destroy only Mold covering the yellow placement plates.
- Place two Calibration Units on the cleared plates; activate Platform B’s Tuning Device.
