Gameplay is quite simple. Your VacFighter can be moved left, right, up and down by using the arrow keys. Almost everything that appears on the screen is harmful to you, so practice dodging!

Unfortunately, dodging won't be enough. You'll need to use more pro-active methods if you want to survive the oncoming horde! Use your weapons to take out both airborne and ground-based enemies. As you do so, you'll be rewarded with bonuses and coins which you can collect with your VacFighter.

Coins are tallied up at the end of each wave, increasing your score. When you have accrued enough points, an extra VacFighter is awarded.

After you complete each level, the Research & Development team will install new, powerful weapons for your fighter.
