The Joystick Controller links you with a most profound vehicle of amusement, the rotary wing Word Zapper. It is armed with vertical and horizontal firing lasers and capable of incredible maneuverability. Opposing you is the Scroll - a diabolic device designed to wear out the wrist and boggle the mind. The Scroll parades the alphabet across the screen, taunting you to duplicate a word or scrambled letters flashed at the bottom of the screen. You must shoot each letter in perfect order, and you must match three words or letter combinations within 99 seconds. Sounds easy? Wait until you meet the Scroll's friends, the Asteroids.
