To unlock the Site B option at the main menu, successfully complete all the missions.

More visitors
If you want more people to visit your park, build four or five entrances on all different sides.

Enable the "Seal Of Approval" code to get five stars. Put as many entrances as you can, then open your park. The chopper should appear instantly, and lots of people should walk through the entrance.

Create a no enclosure safari (still fencing off carnivores). Place a large square fence around the area where people arrive in the space. Fill it with dinosaurs that do not eat humans, then create a small gap in the fence to let humans pass through. Place musters there to stop dinosaurs crossing. On the other side of the fence, continue building a fenced-off dinosaur park. If done correctly, your star rating will keep going up.

Before you open the park, set the entrance fee to 5,000 and 100 people will come in at full price. After that, lower it to 200 so that it will be normal, otherwise no one will come again.

Safari ride
Have two large enclosures, one for Jurassic dinosaurs and another for Cretaceous dinosaurs. Fill them both with paleo trees. Keep enabling the money cheats to add as many as possible. Try not to make too many mechanical object too visible, such as hatcheries. Try to hide them with small mountains or lots of vegetation. Have a mixture of herbivores and carnivores in both enclosures. You will then get a rather high authenticity level.

Saving money
To save a little money, build a small enclosure around a hatchery. When you hatch a dinosaur, sedate it, and move it to its cage.

Build your concessions and park entrances inside a fence. Then, run a fence through the middle of the land and make some hatcheries. Also, put some Auto Lures near the fence so that people can see the dinosaurs. This saves time and money, as you do not build individual cages.

Spinosaurus: Rampages
Spinosaurus always go on a rampage sooner or later. Be prepared to kill one and hatch a new one. Never put more than one Spinosaurus in a cage. If you do, one will go on a rampage in the first few months. Never put a Spinosaurus in with other large carnivores. The Spinosaurus or the other type of dinosaur will go on a rampage.

Dinosaurs fights
No dinosaur will fight a Brachiosaur, but you can get many carnivores to fight each other. However, Acrocanthersaurus and Charcardontosaurus will fight each other at site B only when when stressed. They will not fight for territory. T. Rex and Spino will fight Ankylosaurs, Triceratops, and Stegosaurus when they are hungry. The biggest fights are the T. Rex vs. Spino. If Spino, wins they will be impressed. If T. Rex wins, it will not look too authentic. Raptors will not attack each other, Dilophosaurus, or any other small carnivores unless they are stressed.

Rescue The President level
Shoot the Raptors first. Then, run fast and escape. Once they are all dead, take out the Spinosaurus and then any desired dinosaur.
