From GameWatcher: “The first Jurassic World Evolution DLC expansion is out now, the Jurassic World Evolution Secrets of Dr Wu DLC, and it’s got a lot of new features for fans to play with – including extra dinosaurs. There are only two new non-hybrid dinosaurs, and the biggest is the Jurassic World Evolution Olorotitan.”
