E3M4: House of Pain (Doom)

E3M4: House of Pain is the fourth map of Inferno in Doom.

Secrets

 * 1) From the start, go left and walk along the path crossing a blood pool. Resting in the blood at the far end of the room is a teleporter; go through it to reach an otherwise inaccessible area.
 * 2) After passing through the blue door, take the door on the left. Continue along this path through another two doors until you reach a room with three other exits. Take the one to the left (south). Inside this next room is a "<" shaped wall; open it to reveal a secret.
 * 3) From secret 2, return to the previous room. Take the small door to the north. Walk through the lava and drop into the pit. A BFG rests at the bottom. Flip the switch to get out.
 * 4) After going through the red door, you'll be in a narrow hallway with three alcoves to the right. Open the back wall of the third alcove to get a radsuit.

Trivia

 * House of Pain was also the name of a hip hop group who coincidentally had their biggest hit Jump Around released the same year as the game Doom; however, the level name may be a deliberate reference to the band name.
