E3M5: Unholy Cathedral (Doom)

E3M5: Unholy Cathedral is the fifth map of Inferno in Doom.

Secrets

 * 1) In the starting area, take the door on the far left. Open the wall on the left in the following room to get a pair of light amps.
 * 2) On the west side of the map is a wide corridor lined with a series of red brick columns. There is a door on the west wall; continue through to reach a not-so-secret area with a soul sphere and plasma rifle.
 * 3) In the northwest of the map there is a bright red room with damaging floors. On one of the walls here is a pair of blue symbols. Open the section of wall between them to get a radsuit.
 * 4) Take the teleporter in the aforementioned red room. You'll be taken to the center of the courtyard. The southern of the four structures surrounding the center teleport will have opened, and contains a yellow skull key.
 * 5) With your newly acquired yellow key, make your way to the east end of the courtyard. There is some glowing red "writing" high on the wall. Open the wall below and slightly to the right of the symbols to get a chainsaw and another soul sphere. To exit the courtyard, take the teleporter in the northwest.
 * 6) From the room you end up in after exiting the courtyard, go through either door, then the door next to it on the other side. Walk through this teleporter and you'll be taken to the courtyard center again. The structure north of the central teleport will open up; inside are some goodies.
 * 7) In the north of the map is a corridor shaped like an upside-down "U". Search the outer walls on the western side of this corridor. One of them will open, leading to a secret area overlooking the bright red room from earlier.
 * 8) At the north end of the map is a red brick room with four crushers guarding switches (the blue skull key is in this room as well). Press the switch in the southeast crusher and three alcoves will open on each side of the room. The one containing a rocket launcher (the middle one on the east side) counts as a secret.
 * 9) Go through the teleporter in the southeastern corner of the courtyard from one of the doors inside the building (i.e. not from the courtyard itself). Like secrets 4 and 6, one of the structures surrounding the central teleport will open up; its inside counts as a secret.
 * 10) Same as secret 9, but use the southwestern teleporter. Again, you must enter from inside the building rather than the courtyard.
