The Lone Patrol is a shooting game! The aim of the game is to protect your base by shooting all the enemy soldiers before they get to you! Also protect as many survivors as you can, and be sure to watch out for you ammo and your time! Don't forget to keep an eye out for new weapons too, as they'll help you defeat the enemy easier!
