RHEM Hints
Getting to the Pentangle Complex
1 of 5: When you return to the Round Building after exiting the radio complex, you'll be entering the building through its lower west door. Climb up the ladder and exit the building again through its upper west door.
2 of 5: Go north to the manhole building, then climb down and head south to come to the Round Building's lower south door. Press its call button to get the walkway mechanism to bring the ladder around to the south side, then go inside and climb the ladder.
3 of 5: Go through the door near the ladder top to get back to the control room. Use the walkway rotation panel to set it to connect the south and east (down and right) exits. Then leave the control room, find and go down the ladder, and leave the building through its lower east exit.
4 of 5: Head back to the Four Way Tower, then go south from it and make your way back around and north to the square building. This time, though, don't enter the square building, but take the pathway that branches east from right in front of it. You'll end up at another door to the round elevator tower. Press its button to open the door. (This was made possible by pressing the rotate button near the other upper door as you were on your way to the simulation control area.)
5 of 5: Enter the elevator and take it down to a lower walkway. That will take you back into the square building via the rotating doorway that I sure hope you reset like I told you to earlier. Go through it, then follow the only path available until you reach the vast pentangle complex.
