Jurassic World: Evolution is out tomorrow and it's awesome, but when you start the game most dinosaurs will be locked. The hardest animal to unlock is the Indominus Rex, the gene-spliced monster of the Jurassic World movie that caused the park to collapse.
Hopefully you'll have more luck, as we show you how to unlock the I-Rex in Jurassic World: Evolution! It's part of the late-game content and is a real challenge to get... and even more of a challenge to keep happy. Good luck.
