MAP11: Circle of Death (Doom II)

MAP11: Circle of Death (the name  'O' of Destruction is however shown on the automap) is the eleventh map of Doom II. It was designed by John Romero and uses the music track "The Healer Stalks".

Secrets

 * 1) The first secret does not count towards the level's final score, but does contain an artifact. From the start, follow the path along to the right and take the next right through the doorway into a new area. You should be facing a set of stairs. Turn around, and look for the pool of blood on the ground to the left of the doorway you entered from. The wall behind the blood can be walked straight through in order to get the soul sphere behind it.
 * 2) From the secret above, turn back around and ascend the stairs. When you reach the top, a lift will lower back at the bottom of the stairs, along the south wall. Ride this lift up to a chaingun. To the left of the chaingun is a wall with pipes on it. Open this wall and follow the tunnel to the end, where you'll land on an otherwise unreachable platform with a blur sphere on it.
 * 3) After retrieving the blue keycard, return to the main area (the "O"). Along the eastern wall in the northern half of the nukage lake, a small opening will have opened. Go through and take the teleporter at the end to reach the Imp's platform.
 * 4) After passing through the red door, you'll go through a set of automatically-opening metal bars. The wall alongside the northernmost bar can be opened when the bars are opened. Take the passage out to the Hell Knight's cage, containing an invulnerability sphere.
