SPACE FORTRESS (1 to 4 players)

Deep, deep in space lies a defense base designed to guard our home galaxy against enemy alien invasion. Its powerful laser weaponry is our only hope for warding off enemy invasion.

STARTING THE GAME

Choose Space Fortress 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).

The same procedure enters the numbers of players (1-4), the number of bases (1-9), and the intensity of play (1-9). As soon as one base is destroyed, another appears (when more than 1 is entered). Warfare intensity becomes greater as the intensity number increases.

PLAYING THE GAME

Press the trigger on the hand control to begin the game. Instantly enemy ships appear, hurling deadly fire balls toward the fortress.

Aim the laser gun by shifting the joystick on the hand control toward the enemy ship. Fire the laser by pulling the trigger. Direct fire explodes the ships and neutralizes fire balls. Fire quickly before the fire ball hits and explodes the fortress.

Successful defense provokes the aliens to launch more fire balls, providing little chance for retaliation. Be warned; as the battle continues, tension mounts!

Randomly, an alien kamikaze ship zooms in for direct attack on the fortress. Shoot accurately or it will ram the fortress with its highly radioactive energy core.

Once a base is destroyed, another appears (if you selected a number greater than 1 prior to beginning the game). Once all the bases have been destroyed by each player, the game is over.

SCORING

Points are scored as follows:

Points for each player are shown in the upper portion of the screen. Play continues until all bases have been destroyed. The player with the most points at the end of the game wins.

STRATEGIES FOR WINNING

• Aim and fire quickly or the fortress will be destroyed.
• Fire not only at the alien ships, but also at fire balls launched toward the fortress.
• Learn to anticipate where the next alien ship will appear, and always be prepared to fire.
• When a kamikaze ship appears, aim slightly ahead of the ship in the path it is following.
• By moving the joystick while shooting, shots can be fired in more than one direction with one pull of the trigger.
