Sigil is a free megawad for the original 1993 DOOM® created by John Romero. It contains nine single-player and nine deathmatch levels.
Sigil takes place after E4M8 and before Doom II. After killing the Spiderdemon, Doomguy's next stop is Earth. However, Baphomet glitched the final teleporter with his hidden sigil, which brings Doomguy to even darker shores of Hell. The Doomguy has to fight through this stygian pocket of evil to confront the ultimate harbingers of Satan, then finally return to become Earth's savior.
- Baphomet was only doing Satan's bidding by bringing you back to Hell. Somehow they didn't understand that you're the reason they failed in the first place.
- After mopping up the place with your arsenal, you're ready to face the more advanced demons that were sent to Earth.
- Lock and load. Rip and tear.

Romero created the WAD for the 25th anniversary of Doom. Work began in 2016, with Romero working on it part-time through 2017-'18. It was constructed using Doom Builder 2 by Pascal vd Heide. The game is designed to be a "true fifth episode" of the original Doom however the mod is presumably non canonical. Betheda's slayers club calls it an 'unofficial sequel' and 'revisionist history' to the series canon. Bethedsa has since released it and other unofficial add-ons with their PC and console ports.
Revising the history for ending of Doom + Thy Flesh Consumed from being Earth, to being a limbo/purgatory universe would beg the question on how Daisy got there. Granted if one simply ignores 'Daisy', where the story just has him traveling between various hell dimensions between Inferno, Thy Flesh Consumed, and finally SIGIL, it simplifies things (ignoring one of the sillier aspects of the original Doom story).
