Space Cowboys by Paul Stamatiou, Rohan Bansal, Mike Alberghini

Our game will have two players on the field. Each player can move freely and fire one homing missile at the other player.The homing missiles will home in on each player. If the player who fired it is moving, the missile will move towards them at high speed. If they are standing still, then the missile moves towards them slowly.If your missile gets to the opposing player before you get shot, you get a point.
