Car Defender is an addictive base defense game in which you have to repel the attack of alien vehicles with the help of military vehicles. Click "Play" to get started. Click on the cars below – and they will be transferred above. Now drag one of the same to another to get more powerful military equipment. Click on the blue boxes next to the vehicle to appear. Connect it again to a steeper one. Do this constantly to get stronger fighters. Compose 1+1, then 2+2, then 3+3. Arrange defenses in a row to repel an attack along the entire line. Do not let the enemy get close to you, so as not to die.
