Developer Frontier has shared more information about several new and improved aspects of Jurassic World Evolution 2.
They do this on their forum, where they highlight some changes and additions. For example, in part two, dinosaurs create territories within their enclosures based on their environmental needs. If this territory gets too small, they will want to expand it. In addition, dinosaurs move a lot more in this game, so players have to think more about where exactly they place their Viewing Galleries.
The dinosaurs have also acquired more different behavioral traits and they respond better to their environment. Frontier has added new animations for dinos resting, socializing, walking, running, hunting and fighting. Carnivores hunt more often in groups and do so more intelligently. However, dinosaurs that are more likely to be hunted are also smarter at avoiding the dangerous beasts. This increases the chance that they will survive an attack and that medical help can arrive in time to save them.
Jurassic World Evolution 2 is slated for 2021, although a launch date has not yet been announced.
