- Distracting T. Rexes
It is not possible to kill T. Rexes when you are a human. The only exception is the smaller version of a Rex in The Cave mission. Other than that, all your guns and spears can do is distract the T. Rex to come after you instead of your comrades. In most missions you must have the T. Rex come after you so that your comrades can open a door or complete an objective of some sort. Do not waste all your ammunition on a T. Rex. A few rounds of fire should be enough to distract it.

- Killing V-Rexes with Kong
The very first time you fight the V-Rexes, there is a ledge which you can climb onto so they cannot attack. However, once you are up there, you will be attacked by the flying dinosaurs. They are not hard to defeat. When you are up there, go into Fury mode by repeatedly tapping Y until Kong smacks the ground. While in Fury mode, attack the V-Rexes one at a time. After you have hit one of them three times with A, they will be temporarily knocked out. You can then perform a finishing move by repeatedly tapping B or A. If done correctly, Kong will snap the V-Rex's jaw in two or throw it.

- Easily killing smaller dinosaurs
Use the following trick to kill a smaller dinosaur, such as the Velociraptor, easily. Throw a spear directly in its neck or head. Notice: The spear does not need to be on fire.
