Low Security FenceEditThe first type of Fence in the game, and the cheapest as well. It can easily contain every Herbivore in the game EXCEPT Triceratops, which requires Medium Security Fences instead. Albertosaurus is the only Carnivore that can be fully contained with this type of fence. If Ceratosaurus is unlocked as one of the first two Dinosaurs in a save file, then you may wish to research Medium Security Fences before adding them to the park. However, as they are relatively tame carnivores provided they are looked after carefully, they can be temporarily contained in Small Security Fence enclosures until Medium Security Fences can be researched. Ironically, though it is the weakest fence in the game, the first film uses this type of fence for the Tyrannosaurus paddock, which requires High Security in this game. This may be why the Tyrannosaurus from the film was able to escape so easily. How Ceratosaurus and Dilophosaurus can get past this fence is a mystery, since unlike other Dinosaurs that require a fence type higher than Low, they do not rampage; They go into comas when they reach max Stress instead. The Low Security Fence costs $100 per fence ($300 per section).
Medium Security FenceEditThe next type of Fence in the game, which needs to be researched before High Security Fences can be researched. If you wish to upgrade a Low Security Fence to High Security, it will upgrade to Medium Security first. Triceratops is the only Herbivore that requires Medium Security, where every Small Carnivore except Albertosaurus requires Medium Security as well. This Fence type may not usually be used as much as the other two types, but it does the job to contain slightly more stronger Dinosaurs than those that can be contained with Low Security Fences. A Velociraptor will sometimes attempt to jump the fence as if to test for weak points in the fence, and usually at a different section of fence for each hit. Depending on where such a weakpoint is in the fence, a Velociraptor will either be shocked by it or it will succeed in jumping over it. If the latter happens, they remember exactly where this weak point is should they try and climb a fence again. Due to the risk that a Velociraptor can actually escape it's enclosure even with a Medium Security Fence, it is recommended to keep them behind a High Security Fence, as they will NOT attempt to climb that kind of fence. Triceratops will not try to break down this fence unlike how certain Large Carnivores like Tyrannosaurus will attempt to break down a High Security Fence. The Medium Security Fence costs $250 per fence ($750 per section). It will cost $150 to upgrade from Low to Medium Security for each fence ($450 per section)
High Security FenceEdit
The final type of Fence, which is exclusive to Large Carnivores in terms of requiring this type to be contained. ALL Large Carnivores require this type of Fence. It is the strongest type of Fence in the game, being able to contain every Dinosaur in the game with no issues whatsoever. It has a very armored look to it compared to the previous types, as well as being taller compared to the other types as well. Even though it is the most powerful fence, it IS possible for something as powerful as Spinosaurus to break out of it provided they survive the electrical shocks from the fence. A Velociraptor will not attempt to climb a High Security Fence. Also, only Tyrannosaurus, Spinosaurus, and Carcharadontosaurus will attempt to actually break down this kind of fence; Allosaurus and Acrocanthosaurus will not attempt to at all. However, as long as you simply take care of these specific large carnivores in the first place, they will not attempt to break this fence down just as long as they are not rampaging. The same can be said about any Dinosaur that are known to rampage. The High Security Fence costs $500 per fence ($1,500 per section) and due to this, it is the most expensive fence. It costs $250 to upgrade from Medium to High Security per fence ($750 per sec
