Falcon Patrol 2

Just like it’s predecessor, _Falcon Patrol II_ is a two-way side-scrolling
shooter that sees the player controlling a jet fighting off different enemies.
A small radar shows the positions of the enemies and landing platforms (where
the jet can be refueled and re-armed). The jet is capable of shooting
diagonally downwards now, and there are more versatile enemies. Apart from
helicopters that directly attack the jet, there are also unarmed support
helicopters that drop anti-aircraft guns and radar jammers. There are 15
levels of difficulty and the next level is reached once a certain number of
helicopters is destroyed.
