Neo Geo

The game has only 2 or 3 buttons used depending on the selected transfer mode. Pull the joystick to maneuver the shuttle. The first shuttle mode allows you to fire missiles and laser shots at the same time with the button, but press the alternate mode button for a laser shot and the B button for a missile shot. Laser pulses are used for air attack and missiles are used for air/ground strikes. When the Drone is fired, bonuses can be collected: S for Speed, L for Laser Shots, M for Rocket Shots, and G for Credits.
