Serpen’s MacenWolf release this week features two mods linked by a common theme of “Hell”!
Hell Wolfenstein is an early map set by Clubey (With uncredited contributions from other authors), featuring 8 maps originally made for The First Encounter.
Wolfenstein: The Hell to Heaven (As translated from Japanese) is as suggested a Japanese mod from all the way back in 1996. Created by a modder called Tomohisa Kishihata and collected by Clubey, this game spans 11 levels and was also originally made for The First Encounter.
