In Part 6 of Silent Hill: Townfall, players must manually open the auxiliary lines after progressing through the Remote Systems Control puzzle. The process matters because it unlocks the next stage of the CCTV sequence and requires navigating the AUX Room’s complex switch puzzle.

Players must enter 0825 into the nearby locker to obtain the AUX Key, travel to Level 1 and retrieve the AUX Disk from the AUX Room. The three switch groups then need setting in precise sequences: Line 1 is Up, Down, Up, Up, Down, Up, Down, Up, Up; Line 2 is Up, Down, Down, Down, Up, Down, Down, Up, Up; and Line 3 is Down, Up, Up, Up, Down, Up, Down, Up. Lines 1 and 2 are read right to left, while Line 3 is read left to right; all three indicator lights turn green when solved.
