In Jurassic Park: Operation Genesis, Visitor Shelters are bunkers that protect visitors from carnivores and twisters during park emergencies, with each providing space for up to 40 visitors. A Visitor Shelter will release its occupants once the park emergency is over but will remain closed if severely damaged.Visitor Shelters are important to the park especially during twisters because it will do great damage and also twisters can release some carnivores and might eat some visitors.
