In Air Invaders, your job is to help Dave Lennox destroy the bad air monsters coming from the home's air ducts before time runs out. And if you think that sounds silly, you're right. Anyway, the bad air monsters are using a shield of smaller bad air particles. You'll need to blast through the smaller particles before you can zap the bad air monsters. There are four levels of monsters, with three rooms each, and as you probably guessed, each level is harder than the last. Good luck!
