MAP02: UAC Executive Areas, Interlock (Perdition's Gate)

MAP02: UAC Executive Areas, Interlock is the second map of Perdition's Gate.

Essentials
At the start, open the door and go down the stairs to your right. Go up the stairs in front and take the stairway to the left. Go through the opening in front and go down the stairs to arrive at an outside area. Go around the central structure to find its entrance, then climb up the stairs and collect the blue key. Retrace your steps to the start until you're near two blue torches, then face right. Go through the opening on the right, down the stairs and flip the switch in this room.

Climb the stairs back up and make a hairpin turn to the right. Once at the bottom of the stairs, take either opening in front and enter the teleporter at the end. Look towards the window on the right in front of you, then go forward and make a hairpin turn to the right to find a switch. Press it then take the teleporter again to return to the previous area. Take the previous stairs back up and make a hairpin turn to the right. Go down the stairs, continue forward and use the left teleporter. Go forward and follow the path to find the red key. Grab it and retake the teleporter to exit this area. Return to the blue torches to spot a red door in front, then go through it. Make your way through the rooms to find the exit door, then open it to find the exit switch.

Secrets

 * 1) After the start, instead of taking the stairway on the left take the right one instead. Go through the opening and open the wall in front of you to access two medikits and a chainsaw. (sector 33)
 * 2) In the blue key area, a section of the south wall is misaligned. Open it to find two stimpacks and a partial invisibility. (sector 95)
 * 3) After taking the first teleporter in the level, face the window on the right in front of you then move forward and turn right. This will lower the easternmost window on the south wall to the ground, allowing access to eleven health bonuses.  (sector 264)
