The story takes place after the events of the movie, except with the presence of Procompsognathus. You are sent back to Jurassic Park to retrieve dinosaur eggs from around the park and put them in an incubator. You only have 12 hours to retrieve one egg from every species of dino in the park. Unfortunately, shortly before arriving at the park, the player's helicopter crashes.
At the end of the game, the player character discovers that it was BioSyn that shot down your helicopter and that they have arrived on Isla Nublar. The player must then fight their way through BioSyn personnel and steal their helicopter to get off the island and ultimately win the game.
