Rocket Command

Interterrestrial beings are erupting from the earth's core in an attempt to take over the surface! As the Rocket Commander, you have installed a battalion of rockets at the top of the volcanic crater where the magma beings are launching their craft. It's up to you to destroy these molten enemies before they launch into the sky! If your rockets destroy enough invaders, your leader will allow you to install more rockets to continue your campaign. You must be on your toes, because there's not much time to aim when you are down to your last few rockets!
