Generator of Evil is a single-level PWAD for Doom II meant for Boom-compatible source ports. It was designed by Alexander S. (Eternal) and uses the music track "Dracoid Ruins Battle", originally from Lands of Lore: Guardians of Destiny.

Generator of Evil is the oldest of Eternal's releases on the /idgames archive, and it is also the author's first publicly released slaughter map.

Other points of interest[edit]


  1. At the northwest end, go to the east side, take the steps, and open the big door. Immediately press the switch north of the door to open the door east of the one you took. This has a berserk pack, a soul sphere, and an invulnerability. (sector 152)
  2. Open the blue door leading out of the northwest end and take the first set of steps. In this corner, shoot the small recession in the east wall to lower the south wall, leading to a soul sphere, a box of shotgun shells, a medikit, an invulnerability, and energy cell packs. (sector 195)
  3. Take the door leading to the north area, then take the east path. In this room, use the south wall with the pool of blood to lower a wall to the northwest, which has a soul sphere. (sector 579)
  4. In the cyberdemon maze, go to the northwest switch. Head east from it to the second path going south, and take it until you find a wall with a skull. Lower that wall to get boxes of shotgun shells, partial invisibility, energy cell packs, and an invulnerability. (sector 626)
  5. In the cyberdemon maze, go to the southeast switch, then head northeast from it and open the north wall with the skull to get energy cell packs. Open the north wall here to get medikits, a soul sphere, and an invulnerability. (sector 631)
  6. In the cyberdemon maze, go to the northwest switch. Head east from it and take the first path south. Find a wall with a skull on it and lower that wall to get an invulnerability, a BFG9000, medikits, a megaarmor, and energy cell packs. (sector 643)
  7. In the room with the demon carving of blood on the floor (southwest of the hub), open a wall just to the right of the steps to find ammo, medikits, and a megaarmor. (sector 759)
  8. In the wooden maze at the east end, go to the east side, and at the east column with a switch, use the backside with the black banner to lower the column. This has a soul sphere. (sector 804)
  9. After opening up enough rooms in the wooden maze, so that you are at the tenth row of blocks lowered, head north on the east side and use the darkened terminal to find a switch. Shoot it and run south and southwest to a lowered column with an invulnerability. (sector 823)
  10. In the same row as Secret #9, head to the west wall and lower it to get a green armor. Open the wall behind it for a secret passage leading to an energy cell pack (lower the northeast wall to get an invulnerability) and passage to a soul sphere. (sector 914)
