(PCWorld)

Today´s the 25th anniversary of Doom, if you can believe it. On December 10, 1993 people first stepped foot onto a demon-infested Mars, courtesy of id Software. And while id´s upcoming sequel Doom Eternal is the next official follow-up, Mr. Doom himself a.k.a. John Romero today revealed his own personal celebration of Doom´s legacy, titled Sigil.It´s an enormous Doom WAD basically (or colloquially: a megawad), a mod like any of the other hundreds of mods out there-except this one´s built by Romero himself, of course. Romero´s calling it an `unofficial spiritual successor to Ultimate Doom´s fourth episode,` making it Doom´s fifth episode in all-but-name. Romero says he´s been working on it `while I was on vacation or in the evenings` for the last two years, prepping for the anniversary. (Yes, Romero´s also working on something else apparently, and says it `will be done when it´s done.`)To read this article in full, please click here
