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? Can you survive Sub Terra?
In Sub Terra players spend their turn exploring and revealing the tunnel system around them, attempting to survive the various perils of the cave, from floods and cave ins to gas leaks and scree. Players each have a role which gives them specialist abilities, such as an Engineer with dynamite to blast a new route or a Scout to find a route more easily. New tiles are placed from a randomised stack of cave features, which determines whether you'll be hit with a dead end or a range of new options. At the end of each turn, players face the reality of their situation, with a hazard card drawn to determine what danger causes them damage or cuts off their way out of the horror below. These cards are finite, and when they run out, your torches flicker and the air feels tight, and your chance of survival diminishes quickly.
