The PFS classic "Doom" recently celebrated its 30th anniversary, and the creator of the series, John Romero, also "timely" launched the unofficial derivative work "SIGILII" of "Doom". The predecessor of this work, "SIGIL", was released in 2018 as a game to commemorate the 25th anniversary of "Doom". At that time, it was called the "fifth part" of "Doom" because of the name of an unofficial derivative work.

In "SIGILII", which is recognized as the "sixth" unofficial "Doom", "FPS Godfather" John Romero provides players with 9 levels, as well as two special levels designed for death matches.

"SIGILII" is available to players as a free version of the game on the official website, but it also provides special soundtrack versions of "SIGIL+Buckethead" and "SIGILII+THORR" priced at 6.66 euros respectively.

In addition, physical versions including floppy disk-themed USB drives, illustrations, stickers, themed coins, T-shirts, etc. are on sale (some have already been sold out).

The autographed physical version enclosed in a large box with a beautiful cover of Devil Sheep Head is now on pre-sale. The standard signed version is priced at 66.6 euros, and the collectible signed version is priced at 299.95 euros.
