Two things popped into our minds when we first saw the corridor in this picture. The first was Titanic, and the second one was Deep Blue Sea. Honestly, we can’t tell what’s worse, slowly drowning in freezing cold water or getting eaten by a giant mutated shark.
Apparently, the water level continued to rise as the person who posted this descended further downstairs. From the looks of it, it’s either a flooded metro station or a sinking ship. Hopefully, it’s not the latter.
