Secrets

 * 1) From the platform the red keycard was on, drop down to the east to get a berserk pack. Lower the tan crate to get back out. An alternate way to get this secret is to lower the stack of two medium-sized grey crates in the corner of the room by pressing its northern side, and then ride it up and over the larger tan crate. You cannot get the red keycard this way, however.
 * 2) Go through the teleporter in the room with the red keycard and then follow the ledge outside to a shaft in the wall. Drop down into it while pushing against the north wall, and you will land on another ledge. From there run down onto a platform holding a chaingun.
 * 3) After passing through the red door, follow the corridor along until you reach the part where it gets narrower. Instead of going through the narrow passage, turn to your left and open the wall to reveal a secret cave.
 * 4) Once inside the building locked by a yellow key, follow the lava river south to the end, and flip the switch there. this raises a staircase back in the previous area. Walk up the first section of these stairs, but before turning left to continue up, open the corner wall in front of you. This reveals a secret teleporter (Note: due to an editing error, the secret area will not be triggered unless one walks on the teleport pad using no clipping. Otherwise, you'll go through the teleporter without causing the secret to register).
 * 5) At the end of the staircase mentioned in secret #4, ride the lift to the roof of the building. From the top of the lift, turn east and run as fast as you can through the opening in the parapet ahead. You should land on an elevated platform in the lava pit below. Flip the switch there. This opens a passage at the east end of the lava pit. Entering this secret opens the exit to the secret level (secret #11).
 * 6) Return to the roof of the building (from the previous secret) and follow the balcony north. Quickly drop back down to the lowest floor of this building and follow the lava river north through a small tunnel to a timed lift. Ride it up to another portion of the building's roof.
 * 7) Inside the southeastern building requiring the yellow keycard, walk staight ahead to lower a lift. Follow the path a short ways and start running up the stairs when you reach them. You will hear several doors open. When you get to the top of the stairs and across the bridge, make a u-turn to the left, and run across into the alcove with the megasphere.
 * 8) See secret #7 (this area counts as two secrets).
 * 9) When you run across the bridge mentioned in secret #10, a wall opens behind you. Go back and drop into the hole behind it.
 * 10) Take the teleporter in secret #9 to be taken to another secret area.
 * 11) Return to the building from secrets #4-9. Follow the lava river south again and enter the previously unopened tunnel leading to a teleport to the secret level, MAP31: Wolfenstein
