FLUX is a cooperative puzzle game for two players with a focus on communication and interdependencies. Each of the players has to choose one of the two protagonists. One character is controlled with the mouse, the other one with the keyboard or a gamepad. Together trapped in a world of abstract shapes and elements, there is not much explained but a lot to be discovered. Each chamber needs to be explored, touched, listened to or be observed in order to reach the exit. FLUX brings a new approch to a local coop experience. The asymmetric controls force the players to communicate and develop strategies to solve puzzles. The players are challenged by a variety of ever changing level designs and mechanics.
