Getting to the Radio Complex
1 of 14: As with the water tank area, getting to the radio complex is going to be quite a chore. Start by leaving the Four Way Tower through its north exit.
2 of 14: You'll end up in the east half of the brick building (you've already seen the west half). When you come to a water-filled gap in the walkway, look down and press the top button on the nearby control box. Then you can cross it. After you do, turn around and look down again to find another control box. Press its top button to slide the walkway away again (and back to the west half of the building).
3 of 14: After doing that, continue on and up the stairs to two little rooms, one of which will be filled with water.
4 of 14: If you did as I said before in the square building about pulling the lever next to the large pipe segment, the water will be in the right room (as you face them) and you can enter the left room and go through the secret door in its back wall.
5 of 14: Continue along the secret passage, climbing down a ladder when you encounter one, until you come to a path-blocking thing with a red button next to it. Press the button to turn the rotating doorway so that you can go through it. On the other side, press the second red button to rotate the doorway back to the way it was. That'll be important later on as you travel to the pentangle complex.
6 of 14: Continue along until you come to the elevator tower. Press the lower red button first to call the elevator, then the upper red button to open its doors. Get inside it, then close its doors (bottom button) and go up (top button). After the elevator stops, open its doors (next to bottom button) and leave it.
7 of 14: As soon as you exit the elevator, turn around and close its doors (top button) and rotate it (bottom button). Doing this will also become useful when we're ready for the pentangle complex.
8 of 14: Follow the path past the elevator along, ignoring the small side section with the telescope, until you come to the simulation control area. Enter the little control shack and find the panel with red and green buttons and four empty squares along the bottom.
9 of 14: Press the red button to get a view of a nearby locked door. That'll also put zeroes in the four empty squares. Press the small button to the right of each square until the four digits read: 8527. Then press the green button to open the door.
10 of 14: Exit the control shack and head around to the building with the now-open door. Go through it to get to the rotating bridge region.
11 of 14: Near the spot where you could cross if the bridge were rotated, head down the side door and down some stairs until you find where you can cross the bridge as it is now. Open the panel that's across the bridge and press its button until the right and bottom exits are connected. (Yes, this is affecting the Round Building's rotating walkway mechanism. You're arranging things so that you can exit that building from its lower west exit.)
12 of 14: Now turn around and go back across the bridge. You'll soon come to a spot with a power meter on the wall. Press the button near the top to get the meter indicator to go from 0 to 1. The bridge is now powered and ready to rotate.
13 of 14: Return to the control shack in the simulation control area and use the panel that's on the wall opposite the shack's door. Press the red button to get a view of the rotating bridge, then press the green button to rotate it. Now head back to the bridge area and cross the bridge to get back to the Round Building.
14 of 14: You'll be going in the Round Building's upper north door. After you do, head down the corridor, climb down the ladder, and exit the building through its lower west door. Follow the path along to FINALLY get to the radio complex! Was that a lot of work, or what? Fortunately, there's very little to do by comparison in the actual complex.
