ArmorLock has a great tutorial for you to play in order to get used to the game. The many stages of the game will take from on foot to driving vehicles and even more. You'll have a variety of weapons to choose from which you will toggle through with the one through seven keys. Use the mouse button to shoot. Watch your ammo in the lower left hand corner and be sure to reload with the R button before you completely run out so you're not caught without defense. There are different difficulties to choose from and each level has its own objective. Good luck playing ArmorLock and have fun!
