tip: Try and save at least one or two smart
                 bombs for the final battle of each campaign.

                 tip: The computer likes to blast large bursts
                 of fire in a horizontal arc, so when
                 approaching gun emplacements, come in at a
                 steady altitude. Then, as the guns open up,
                 drop about a third of your height and keep
                 approaching, guns blazing. Hop back up again
                 when you see another burst being fired.
