Released in 2022 by Frontier Developments for PC, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X|S, the Dominion Biosyn Expansion is the largest downloadable content package for the park-building simulator Jurassic World Evolution 2. Drawing from the events of the Jurassic World Dominion film, it introduces a new story campaign set within that narrative context. The expansion adds previously unavailable prehistoric species to the roster, including feathered dinosaurs, broadening the range of creatures players can breed and manage. A new Chaos Theory scenario is also included, offering an additional structured challenge alongside the main campaign content. As a strategy and simulation title, the base game tasks players with constructing and overseeing dinosaur habitats, and this expansion extends that experience with fresh species, environments, and story-driven objectives tied to the Dominion setting.
