Our take on Somnium Tenebris
The defining structure is a five-player investigation beneath the ocean: the team gathers evidence to identify a massive creature, manages its attention, and must return to the surface alive.
What is Somnium Tenebris?
Somnium Tenebris is a cooperative investigative horror game for five players, set beneath the ocean in a Lovecraftian world.
Teams use a submarine’s detection equipment to search for evidence and identify a huge creature while avoiding excessive attention. Each dive generates a different underwater environment, arrangement, and set of challenges. Before an investigation, players choose a difficulty that affects the map and creature behavior. Investigations include seven possible evidence categories, ranging from physical remains to electromagnetic signals, and may involve any of 15 creatures inspired by deep-sea fiction. Players can join open sessions or create private lobbies for up to four friends. Successful investigations provide currency for character customization, while survival requires reaching the surface alive.
