MAP03 (Brotherhood of Ruin)

MAP03 is the third level of Brotherhood of Ruin. It was designed by Kristian Aro and uses an unnamed MIDI composition by Paul Corfiatis.

Essentials
You will immediately be attacked so grab the super shotgun as quickly as you can. Head towards the stairs in the southeast and go through until you find a switch. This is an unmarked red key switch, so ignore it for now and head to your right. Follow the hall into a chamber and go outside and press the switch. Now backtrack into the big open space, and bars will have been lifted close to the stairs in the southeast. Head straight through the passage east and north to a switch, then back and up the small steps into a new passageway. Follow it around to the red key, then go back to the red switch. Flip it, and bars to your north will be opened. Follow the path outside and across a bridge into the next chamber. The teleporter here leads to Secret #3, but when you go back, look out because you will be surrounded by revenants. Go west and under the water to the next chamber. Go outside again, and hit the switch at the dead end to the north in order to proceed to the next door. Pressing the next switch in this room with the inescapable blood pits opens a door behind you on your right. Follow this path to a tomb and a switch which opens up the eastern path leading to an exit. Approaching the exit switch causes it to be barred for approximately nine seconds while you fight a revenant and an arch-vile.

Secrets

 * 1) The ziggurat right at your starting point can be climbed on the northwestern side of it. Keep climbing it until you see nine cacodemons and a soul sphere. (sector 57)
 * 2) In the northeastern portion of a map is a chamber with a teleporter in the middle. Take this teleporter to reach a caged-in room with two revenants, a megasphere, and a box of rockets. (sector 16)
 * 3) After you go through the water in the north end of the map, look on the Mayan frescos in this room. Press on the one with a bloodied appearance to lower a plasma gun. (sector 422)
 * 4) (sector 253)
