An unreleased Intellivision title from 1983

Cut across fire in a Time Sailer, cruise under water in a Submarine, fly through thin air in a Zeppelin, or roll across the Earth in a Tank -- but never stop firing at the dreadful creatures that beset you! Shoot them down with the fireballs you control and they'll turn into black numbers. When you shoot enough creatures, you get a chance to solve exciting mathematical equations...and score big points! Hurry, for every second counts! Have fun! 1 or 2 players. 1 little man under your control when the game starts, 4 more in reserve. 4 different environments to choose from! Simple to more complex equations. Both "scratch pad" and "solution" areas to work on. Choose from 48 skill levels. Transport Houses found in every environment to give you bonus multipliers. Progressive scoring setup, according to your skill level and speed in solving equations. Automatic transfer to a higher level once you've mastered the one you're on!
