With the severe reduction of the human population, sightings of creatures long-thought to be extinct have grown more and more frequent. Use the Creatures-Add-On to throw up to four entities into your game that act independently of the players. Some of them are aggressive, others are well-disposed and interact with the player, while still knowing how to defend themselves. Creatures move and fight entirely on their own and influence the game with their unique skills. Give your Rapture a wild, untamable twist.
