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 east of your starting point can be climbed from the northwestern side of it. Keep climbing up until you reveal nine cacodemons and a soul sphere sitting in the middle of the top. (sector 57)
 * 2) Get the red key and enter the compartment that opens to the east after grabbing the key. Press part of the south wall to get health bonuses and an energy cell pack. (sector 253)
 * 3) 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. Be careful coming back though, because after using the teleporter in the secret area, you will be surrounded by two Chaingunners and two Revenants (on Hurt Me Plenty). (sector 16)
 * 4) After you go through the water on the north end of the map, look at the Mayan frescos in this room. Press on the one with a bloodied appearance (it's the eastern side of the northern column) to lower a plasma gun. (sector 422)
