How To Kill The T-Rex
Carnivores is a pretty easy game till it comes down to the T-Rex. If you though using cheats to kill him would be super easy, then think again. The only way to kill a T-Rex is to shoot him in the eye. The only weapon you can use that has the capability of an exact precise shot would be the sniper rifle. I used cheat mode to fly, cause' if you get anywhere near him on the ground, then your toast.
