"Perhaps of all the monsters, the giant shark is the most enduring. It incorporates virtually every element that we require of our mythological sea beasts: great size, mysterious habits, verified anthropophagous inclinations (i.e., attacking and eating humans), and a history that goes back to the beginnings of recorded time. More than Leviathan, more than the sea serpent, more than the Kraken, Megalodon may be the ultimate monster." - Richard Ellis, Monsters of the Sea
addons? "back in the days" you had to manually dl all the models and c&p these yorself but seriously. yeah, it's the shark from crysis with a ridiculous size. can't really show a comparison here since there's no human or submarine or whatever. and a lot props from all sorts of games. portal 2, skyrim and many more.
