Air Defence 1 is a shooting game on flash-game.net in which you shoot planes and protect your base. When the game starts, your mission is to defend the communications tower. Numerous enemies’ fighters and bombers fly towards the tower and release bombs above your base. You must prevent the attacks from your opponents. You can use your mouse to aim and press space to shoot with cannon. Then build a base and buy upgrades for your defense. The more planes you shoot, the more cash you can get. Then you can afford to repair tower, gain extra shot damage, extra bullet speed, buy computer AA-gun, reduce reload time and increase 10% larger explosion. But once you are shot too many times and your hitpoints decrease to zero, you will lose the game. Are you ready? Shoot now.
