Shoot down enemy planes (The gray ones), while avoiding the friendly ones (blue planes), to get points. You lose points if you let a gray plane pass, or shoot down a blue one. Every once in a while a supply crate will fall, if you shoot a green one it will give you a short boost, or replenish/multiply your current ammo, or even give you more life, while the brown ones permanently upgrade you gun. A bomber will come every 1-2 minutes, which you can shoot down, and you should before it drops the bomb, which you can also shoot down, but if you don't, you'll lose a life. If you lose all of your lives, you lose (Note, World record calculates after you lose, since you can lose points).
