What do you get when you combine Asteroids with slide-and-shoot games like Atari 2600 Space Invaders and Atari 2600 Galaxian and throw in a little Atari 2600 Kaboom! for good measure? You get Atari 2600 Astroblast. You start out with 10 lives and use either your joystick or paddle to blast asteroids, UFOs and sonars out of the sky. Atari 2600 Astroblast is unique in that you actually lose points for missing the rocks, although your endgame score is determined by the peak score you achieved over the course of the game. Using your paddle is highly recommended as it offers precision targeting difficult to achieve with the joystick.
