A few quick tips.

            þ Usage of your radar is normally a good source for finding enemy
            craft. Looking in the distance of the battle screen is a more
            succesful method, as you have a longer range here.

            þ Catching enemy craft by surprise is a good way of getting the
            upper hand on them.

            þ Smaller enemies can be destroyed, by being run over at high speed.
            Using this method will save using up missiles unecessarily.

            þ Usage of mines (especially indoors) is a good way of destroying
            any persuing enemy craft. They will continue along your path until
            they meet a bitter end by manouvering over your mines.
