SigilSigil

Created by id Software co-founder, John Romero, and released as an episode-sized mod consisting of 18 new maps, Sigil fits in between the timelines of Doom (1993) and Doom II. Baphomet, the gatekeeper of Hell, “glitched the final teleporter with his hidden sigil, whose eldritch power brings you to even darker shores of Hell. You fight through this stygian pocket of evil to confront the ultimate harbingers of Satan, then finally return to become Earth’s savior.”

A remastered version made in the KEX Engine, community-published mod support, original midi soundtrack or the modern IDKFA version by Andrew Hulshult, improved performance with multithreaded rendering, BOOM source compatibility, accessibility options and translated into eight new languages.
