Secrets

 * 1) Open the yellow door in the red key room and jump into the damaging slime at the north end. Head behind the northeast cage and use the wall where the pool of blood is to open a passage. After you take the lift up, head west to the next lift and take it up. You will find shotgun shells and a soul sphere. (sector 509)
 * 2) In the arena with the chaingun at the north end of the map when you teleport to the big block west of where the chaingun was and leave it, the cages around you will reveal arch-viles. There is a switch on the north block, which requires an arch-vile jump to reach it (the best way to do this is to get the invulnerability on the west block when you teleport and slowly inch off of it to trigger the cages opening. When you reach the north block, hit the switch and quickly run all the way east and into a brown compartment with a blue torch. Enter the alcove before it closes. Use the switch to leave, then go south and then west to the teleporter. This path leads to the secret exit. (sector 214)
 * 3) At the hub area on the west side of the map, using the skull switch that appears opens up a switch on the west side of the column, which in turn opens up a passage behind you. Take it to a room with a soul sphere and grab it, then use the southwest switch to return to the hub. There will be a switch on the east side of the column this time, which opens up a compartment to the northwest with a teleporter. When you teleport, use the skull switch and enter the next teleporter. Back at the hub, head to the compartment just under the northwest one with the mancubus inside it. Press on the back wall here to find a stimpack and a switch. (sector 914)
 * 4) The switch in Secret #3 opens up a passageway in the lift that led down to the hub. Lower the lift using the lit switch to its left and enter the passage which holds a medikit, a green armor, and partial invisibility. (sector 890)
 * 5) In the southwesternmost room, there are four green torches around this area. Head to the north side of the northwest torch and use it, then go to the room east from the torch area and through the opening in the red wall. When you teleport, you will find stimpacks, energy cells, a plasma gun, and a megaarmor. (sector 476)
 * 6) The sector in front of the secret exit switch counts as a secret. (sector 996)
