You play as a group of miners trapped underground and need to work together to try and find your way to a lift and back out safely. The game starts with players drawing a tile and then placing their markers on the tile. Each player then has a chance to perform a certain number of actions within a turn which includes movement, placement of new tiles and picking up/using objects found in the mine. Every so often rockfall may happen, forcing players to need to dig out of these before continuing. Players also have to manage their energy and weight levels to stay alive and move at a sufficient pace. The game is one when all players are able to make their way successfully to the elevator shaft out of the mine. Along the way, crystals can also be mined and the surviving player with the most crystals, wins the game. —description from designer
