Will you dare to participate in this action game? Then welcome to a dark fantasy world where players are completely devoid of light. You will become one of the Couriers – people who investigate why people died here before. You will have to uncover a story that unfolded here before the world was completely covered by darkness. To do this, players need to choose one of five characters, each of which differs from the other in style of play, and then go on an adventure full of enemies and trials.
