Sub Terra is a cooperative survival horror board game. You and up to five friends are cave explorers who have become trapped deep underground. You must quickly explore a tile-based cave system to find the way out before your flashlights die and you're lost in the darkness forever.
You'll need to work together to overcome deadly subterranean hazards - stick together for safety, or split up to cover more ground. One wrong step could knock you unconscious and your friends will need to stage a rescue. Light and hope are scarce. And worst of all, you don't think you're alone down here...
