In Jurassic World Evolution, Indominus Rex is developed in the laboratory. For that you must first meet the following conditions.
- Since the Indominus Rex is a mix of the T-Rex and a Raptor, you must first have 100% researched the genomes of these animals.
- Then you must have unlocked four islands (Sandbox Island does not count) so you can build four research centers. As far as we know, you can only build one research center per island and you need four of them. Have you built four research centers, you can almost breed the Indominus Rex.
- Go to the menu of your research center and select the option Genetic Research. Between the two honeycombs of research, another hexagon should now be unlocked below, which means crossing projects - this point you must now explore.
- Once the research is completed, you can breed the Indominus Rex in the Hammond Development Lab. Of course, you can also modify it, but the viability of the hybrid may be so low that you will probably lose a lot of money. Boost viability with the Hammond Development Lab Upgrade Success Rate.
If you been able to create the Indominus Rex with the help of in-game currency, then remember that only one should keep him in a pens. There are other ways that the creature understands itself to some extent. These include, for example, raptors.
