Deivisceris is a four-player role-playing tabletop game that focuses on themes of horror. It looks into ideas from the horror genre as a whole while combining aspects from the body horror and cosmic horror subgenres to create a discomforting horror experience. The game features illustrations and written events with a choice-based narrative that can have multiple outcomes depending on a player's decisions, stats, and items. Deivisceris utilizes randomness in order to create a new experience each time it is played through randomized characters and a randomized game board that is built up as it is played. The game reveals its narrative through clues within the gameplay, illustrations, and written text as characters enter the game's world blindly. Deivisceris is an immersive tabletop horror experience that can be further expanded on in the future with the possibility of a larger production.
