An army of various enemies is approaching your city. In the new exciting online game Crowd Defense you will have to hold the defense. In front of you on the screen you will see a protective wall on which the cannon will be installed. Look at the screen carefully. The enemy army will move towards the wall. You will have to aim a cannon at enemies and, having caught them in sight, open fire to kill. By shooting accurately, you will destroy enemies and receive points for this in the Crowd Defense game. With these points you can improve your gun and buy new types of ammunition for it.
