Jackal (USA) ROM

Konami brings Jackal from the arcades to your home with this NES port. It's a an action game where you play as some guys in a jeep that drive around what looks like Vietnam blowing up bad guys and saving prisoners. Some of these prisoners give you power ups that turn your grenades into a rocket launcher which can also be upgraded into a more powerful version.
This game can get difficult as danger can come out of nowhere and dying means you lose that precious rocket launcher and prisoners that haven't been airlifted out yet.
