Arcade defense

An arcade styled tower defense, where you switch between three helicopters - each taking care of a part of the defenses. One can build turrets and mortars. Second one collects money dropped by enemies. The last one can drop very powerful, but expensive bombs. Kill enough enemies and the final boss to complete a level.
