League of Lasers is a motion-based game where two teams compete in a mix between football and Pong [2]. Players use `virtual mirrors' to try to guide a laser pulse towards the opponent team's target. The game aims at stimulating interaction between players by making cooperation a vital part of the gameplay, while having them physically move near each other. The game tracks the physical movement of players as the main control actions. A demonstration trailer can be found here: https://goo.gl/v7mu6k
