Deep Strike is a light WWI combat flight simulation. The player pilots a biplane fighter escorting 4 bombers on a fuel depot bombing mission. The game uses a 3rd person view, the player's plane is displayed in the middle of the screen, with the four bombers in front. Enemy fighter can attack from all sides of the screen, and care must be taken not to accidentally hit one of the friendly planes. There is a set course to the bombers' target, and if the planes deviate too much from it they risk being shot down by anti-aircraft fire.
