In Enemy Aircrafts, collect brief upgrades to make things a little bit easier and make the game last longer. Try to stay alive as long as possible and get a very high score.
Use the tools on the screen to move the car left and right. You could also use the Arrow keys on your computer. Move the mouse cursor to aim, and click LMB to shoot. The automatic attack mode can be turned on or off. It goes through bullets very fast, but nothing gets through. Make up for it by picking up the bullet boxes that friendly supply trucks drop. There are also extra lives, more time, protection, and improvements for weapons. The panel at the top shows all the important details. When there are no more continues or when the timer hits zero, the round is over.
Have fun and good luck!
