The concept of the game is that you are in a war in space. You not only fight on the ships, but in space in the fighters. It has some cool features such as "newtonian physics" basically semi-realistc space like gravity and friction (aka you can blast your engines and the turn you fight and still head the same direction will firing wherever.)
