Invaders from space are attacking your home planet. You command a battery of missile bases hidden in protective bunkers. Enter varying skill levels, from novice to professional, in this home version of one of the most challenging and popular arcade games of all time. The invading hordes never stop coming. See which one of your friends can reach the highest score.

ASTRO BATTLE (1 player)
Protect your home planet from the attacking invaders! Score points for each one you destroy, and win bonus points by blasting the parent ships.
STARTING THE GAME
Choose Astro Battle by pressing 1 on the keypad or by using remote game selection (pull the trigger on hand control #1, turn the knob until 1 appears on the screen, then pull the trigger again).
Enter the level of difficulty:
1-Novice 2-Amateur 3-Intermediate 4-Professional
As you choose higher skill levels, the invaders descend faster and drop more bombs.
PLAYING THE GAME
The hand control functions for Astro Battle are:
|Trigger||Fires the missiles.|
|Knob||Has no function.|
|Joystick||Moves missile base left or right.|
The object of the game is to score as many points as you can by destroying the invaders -- before they destroy you! But, be prepared -- your enemy will always be joined by fresh troops!
As soon as the invaders appear, position your base and begin firing your missiles. At first, you will be able to take refuge behind the protective bunkers. However, these bunkers will begin to break away once they are hit by enemy bombs or your own misguided shots.
Randomly, a "parent ship" will streak across the top of the screen. This ship does not drop bombs, but if your missile strikes one, it will explode and your score will greatly increase.
After you have shot several ships, the remaining invaders will become angry and will attack with greater speed than ever before. Once you have destroyed a complete set of invaders, a fresh troop will appear and will be positioned lower on the screen.
At the beginning of the game, you will have two extra bases. Then, after you reach a score of 1,000 points or more, you will be awarded another base. However, no other bases will be awarded for the remainder of the game. The number of remaining bases and your score are displayed at the top of the screen.
The point value of the invaders from top to bottom are:
When you hit a parent ship, you will be awarded 100, 200 or 300 points.
The game is over when all of you bases have been bombed (or crushed), or when you have cleared six complete troops of invaders -- see if you can get through them all!
To play Astro Battle again, press the RESET button (or pull the trigger on hand control #1) and follow the instructions for starting the game.
