Deep beneath the surface of the ocean, at a depth where not even the faintest trace of the sun’s mighty light can be seen, the cold, obdurate blackness holds the future of mankind. It’s here that the underwater metropolis known as Rapture was built with the dream of the top brass of science congregating to build a better tomorrow. As the experiments and theories began to take shape, science defeated common sense, and something went wrong. Something went terribly wrong. As your bathysphere descends toward this revered paradise, you are hit with the sinking fear that mankind may have gone too far. It’s not until you step foot in the ruins of this city that you realize just how real this fear is.
