The “Power Lines” quest in *Control Resonant* requires the player to restore power to three subway stations by placing special calibration units in the correct positions and activating tuning devices. It unlocks after “Arish’s Briefing”, and matters because the restored power is needed for Arish’s plan to use resonants against the threat, after maintenance teams disappear.

Perimeter, East Park and Factory stations can be completed in any order. At Perimeter Station, three units must be placed in the nearest and two farthest yellow squares, with power cores used to access the final unit; East Park involves defeating enemies, clearing mould, consulting notes and using the tuning device repeatedly, including a teleportation effect. The article also notes that the “Extended Rush” talent can help with timed power-core transfers, while a mysterious intercom message from Dr Florez can currently be ignored.
