Tilt your iPhone/iPod up and down for directional/roll control and tilt it side to side for fore/aft thrust control. Touch the missile and cannon buttons to fire your weapons. Visit the "settings" section for audio, tilt, and button layout options. In addition to accessing settings from the app's main screen, they can be changed while a game is in progress by tapping the pause button.
Your aircraft has unlimited cannon rounds to fire, but a limited number of missiles. If possible, save your missiles to attack the bomber or command aircraft at the end of each level (500 points). Four missile will destroy this aircraft, or shoot 12 cannon rounds.
After destroying an enemy missile (250 points), a blue star will be left on the screen. Flying over this star increases your missile count by 1 and adds 50 points to your score.
After destroying an enemy fighter aircraft (100 points), a yellow star or red first-aid symbol will appear on the screen. Flying over the star will increase your score by 50 points. Flying over the first-aid symbol will fix any damage to your aircraft from enemy rounds.
Your aircraft can take four enemy cannon rounds before being destroyed, but will be instantly destroyed by a missile or collision.
Mission 23 has unlimited levels, but difficulty increases with each level, making it harder and harder to advance.
A bonus life or 5,000 points are awarded every 5th level. A bonus life or 10,000 points are awarded every 10th level.
