Technical information[edit]

Inspiration and development[edit]

  • Originally released as a standalone WAD titled Doom Classic 10: Mercurius Pools in July 2003.
  • Another version of the level was also released in July 2003, two days later after the first WAD. It excludes the cyberdemon after some players complained about its placement.
  • The modified version in The Classic Episode, Part 2 adjusts a light level.
