Defender II © 1988 Atari, Corporation.
Your objective is to rescue the Humanoids and eliminate all aliens. You begin the game with three ships, three Smartbombs, about six seconds' worth of Inviso, and enough energy to hyperspace temporarily out of danger. The number of ships and Smartbombs and the amount of Inviso you have left are shown at the top of the screen. You have an unlimited amount of regular ammunition.
Use the left joystick's handle and fire button to maneuver your ship and fire regular ammunition. Press the right joystick's fire button to drop Smartbombs. Push the right joystick's handle forward to activate Inviso; pull it back to jump into hyperspace. When you run out of Smartbombs, pressing the right joystick's fire button activates Inviso. Once your Inviso is gone, pressing the right joystick's fire button will send you into hyperspace.
Defender II has up to 100 attack waves. As soon as you clear the planet of aliens in one wave, the next wave begins. You score points whenever you destron an alien. For ever 10,000 points you score, you earn another ship, another Smartbomb, and more Inviso.
