Fourcast is a four player co-op puzzle adventure game set in a magical world. You play as young star mages who are able to perceive the connections between the stars, although you are inexperienced in that and thus can only do it together. In this world, stars once defined orientation. They formed invisible paths and held the world together. By communicating with your friends and coordinating yourselves, you reveal hidden paths and reconnect the world with the stars. Guided by your master who claims to understand the stars, you are sent to recover scattered shards of the shattered observatory.
