Spiral

Spiral is a single-level PWAD for Doom that was designed by Richard Krehbiel and released in 1994. It is intended more for deathmatch than single-player.

Secrets

 * 1) At the start, take the path to the south. The west wall has a secret door (marked with a greenish texture) leading to a stimpack and a chaingun. (sector 49)
 * 2) Just before the second lift leading up to the yellow door, jump north-east off the ledge through a fake wall to a teleporter leading to a plasma rifle and an energy cell pack. (sector 45)
 * 3) The path east of the blue key containing medikits has a secret door to the south-west leading to a megaarmor. (sector 64)
 * 4) North of the blue key is a secret door leading to 10 health bonuses and a path back to the start. (sector 69)
 * 5) The maze section in the east has an octagonal room containing a single cacodemon. The three southern sections of wall lower on pressing, revealing a teleporter to #3. (sector 117)
 * 6) After going through the blue door in the red key area, there is a secret door in the north-west leading to a chainsaw. (sector 128)
 * 7) Head east from #6 - the south-eastern wall of the first octagonal room encountered lowers on pressing, allowing access to a soul sphere. (sector 101)

Bugs
The northern outdoor part of the level has a rocket launcher which lowers on approaching the marble wall. Stepping back off the staircase causes the rocket launcher platform to rise again - if you are on the platform and it rises to the top, there is no way to lower it and you will be trapped.
