1942/Gameplay

Controls

 * Joystick: Use the joystick to direct the Super Ace in any one of eight directions. You can move throughout a majority of the visible screen.
 * Fire: Press the Fire button to shoot bullets from the Super Ace. You begin the game with a double barrel gun, but you can collect a power-up that increases it to a quad-barrel gun.  If you collect the power-up that provides twin support planes, they will fire a single bullet each whenever you fire.
 * Loop: Press the Loop button to perform a vertical 360 degree dive in the air. While executing this maneuver, the Super-Ace is completely invulnerable to enemy fire.  You can only perform so many of these, however, and the stock is indicated (in the arcade version) by the red Rs in the bottom left corner of the screen.
 * 1-2 Players: Press to start a 1 or 2 player game.
