Blue Submarine 6

As a result of the machinations of the rogue scientist Zorndyke, all land at sea level has begun to succumb to the expanding ocean tides. Billions have died, and mankind is now at war with Zorndyke's army of water dwelling hybrids. Mankind's last hope lies within an international fleet of submarines and the vessel, Blue Submarine No. 6, and the pilots: Kino and Hayami.Together, they and the rest of blue fleet must launch an attack on Zorndyke's base of operations in Antartica before he floods the rest of the world's remaining landmass.
