MAP28: High-Tech Hades is the twenty-eighth map of Perdition's Gate.

Essentials
At the start, go forward and turn right. Flip the switch to the right to raise stairs then open the door to the west. Ahead you see an intersection. Turn left and go straight to a room with computer terminals, then press the switch on the north side of this room. Return to the intersection and this time go to the west. You'll arrive at another room with computer terminals, use the switch on the south side of this room then enter the teleporter to your left. Collect both keys, then enter the northern teleporter from its west side. Go forward, then open the yellow and blue bars and enter the exit teleporter.

Secrets

 * 1) At the intersection near the start, go down the stairs to the south. To the right is a door, so open it and enter the room. On the south wall of this room is a lift, lower it then take it, facing east. As the lift rises you'll spot an alcove containing a plasma gun and a computer area map. Enter this alcove to collect the items and tag the secret. If the lift raises completely before you're able to escape, simply press on it to lower it again. (sector 44)
 * 2) On the room with computer terminals to the south, on the south wall is a screen with static. Use this screen to raise it, revealing a small alcove with two boxes of shotgun shells and two boxes of rockets.  (sector 121)
 * 3) On the water pool containing both keys, enter the southern teleporter from its north side. Don't move after being teleported, then turn around and run forward to reach a water area. Move to the northeast of this area and open the misaligned wall to the west of the waterfall for a supercharge. (sector 102)
