To go along with the 30th anniversary of DOOM, John Romero has released SIGIL II, a second megawad to blast through with 9 new levels. Available free from the official site, or you can buy different editions that come with different things.
Embark on a nostalgic nightmare: Immerse yourself in the dark, demonic world of DOOM like never before. John Romero, the original Icon of Sin, takes you on a terrifying journey to commemorate the 30th anniversary of this legendary, first-person shooter. SIGIL II is DOOM's unofficial sixth episode.
Upon breaching the pentagram of invulnerability in the final moments of SIGIL, Episode Five, you find yourself not on a victorious journey back to save Earth, but caught in Baphomet's cunning snare, catapulted into a new, grotesque domain of relentless torment, unending demon hordes, and an onslaught of heavy metal mayhem!
