This action game and address in the space will put a strain on your sense of spatial orientation! Your mission is to destroy asteroids threatening the Earth with your spaceship without hitting it. Those who have the space sickness, beware!
Arrow buttons (try) to control the direction of your ship, the up arrow to thrust back and down arrow to reverse thrust. The bar "Space" can be reached from the "Ctrl" key to drop a mine researcher and the "Shift" releases a ball of energy.
