About this game

Enter Somnum, a cooperative horror game where you and your friends are trapped in the same mysterious dream every night. To escape, you'll need to work together, solve puzzles, and gather energy while exploring eerie and surreal environments.

  • 👻 1 to 4 player co-op

  • 🧠 Puzzles and team-based objectives

  • 🏙️ Unique levels like a floating city or a maze-like Japanese hotel

  • ⚠️ Time pressure and player-voted penalties between levels

Get ready to dream... or to face your nightmare.
