Take control of the Metal Slug tank on the NGPC once again, this time to defeat the rebel strike force "Phantom." Travel through 38 stages in a non-linear battle path defeating enemy troops and rescuing hostages. Pilot the Metal Slug tank, Slug Flyer combat jet, and the Slug Sub submarine and fire the heavy machine gun, rocket launcher, and fire gun. Two unique playable characters, a list of rescued hostages, and a time attack mode add depth to this side-scroller.
