PS4 NeoGeo Metal Slug 3: Mission 1 (A Couple's Love Land)

The Rebels' first base of operations is in Pallas Island, a once pristine location now rife with mutated creatures above land and underwater thanks to the multiple crashed nuclear missiles that leaked out radiation. Although it takes the entire afternoon, the heroes are able to clear out the Rebels through the whole island. Their exit out by a makeshift bridge is interrupted by a huge hermit crab with a tank on its back.
