Perdition`s Mouth is a deeply immersive dungeon crawl adventure style game set within a collection of scenarios that form an extended campaign. The game has a strong role-play feel to it but each adventure requires no dungeon master due to the automated non-player character action Rondel. Designed as a fully cooperative game, Perdition`s Mouth accommodates from one to six players taking on the role of brave heroes delving ever deeper into the Abyssal Rift to thwart the threat posed to humanity.
