John Romero announces Doom spiritual successor Sigil
Legendary game maker John Romero has announced Sigil, "an unofficial spiritual successor to The Ultimate Doom's fourth episode".
The announcement comes 25 years on from 10th December 1993 - the day the original Doom launched. That's a quarter of a century ago! Just to make you feel old.
Sigil contains nine single-player and nine deathmatch levels, and will be released for free in mid-February 2019. As a megawad, you'll need the original Doom (not the remake) to play it.
