Battle with Hard Shell
Hard Shell appears to be a giant mutated crab. It has purple whiskers, and a green gem in between it's eyes.
Hard Shell spends the entire battle on the top half of the screen, strafing left and right. Its only form of attack is spitting lethal bubbles that can be destroyed by gunfire. The more damage it takes, the more aggressive it becomes with a barrage of bubbles:
Now given the subtitle "Abyssal Predator", Hard Shell returns as the boss of the 5th area, the Man-Made Sea. Unlike the original battle, this iteration of Hard Shell is extremely mobile, constantly moving through a large arena at high speed. It is now immune to damage from the front, and can only be damaged by being attacked from the back or sides, though the player can bypass this defense with the use of the Penetrate or Wave shots. Uniquely, Hard Shell is featured in several set pieces before the actual encounter: the player can see its shadow swimming by overhead in one room, where a smaller, shed exoskeleton can be found, and in another it can be seen attacking and killing a large whale-like creature.
