Planetary Shield is a skill game where you must destroy all the meteorites before they hit the earth and weaken their shields until their destruction. Your armament is a ball of energy that is generated between two satellites and that you can throw at the meteorites as if it were a slingshot. You can also get items that help you in your mission, such as a missile that destroys nearby meteorites, an object that repairs your shield or another that makes you invulnerable in a limited time.
