Commando Raid
You defend your buildings, which are attacked by android commando fighters. Without warning, they appear to capture your buildings and destroy your gun emplacement. First the troop-carrying helicopters fly in and drop android paratroopers to test your defenses. Soon the sky is full of fluttering helicopters and a wave of paratroopers. They must be destroyed! Every paratrooper that lands on a building destroys part of that building. If three paratroopers land on a building. It is completely destroyed and must be considered under command control. Even worse, the androids can now dig a tunnel to your gun emplacement. Each paratrooper that lands on the building enlarges the tunnel. If they are not stopped, they will place an explosive charge under the gun. In the middle of the battle, an airplane may appear. It will drop a devastating bomb that can destroy all buildings and the gun emplacement. You must shoot it down or at least shoot down the bomb it drops. If you miss, it's back to basic training!
