Approach the giant tree in the middle of the nest site with a shotgun, explosive tip arrows, and grenades in your inventory. Shoot a flare at the dinosaur with its head in your line of fire. While the dinosaur's attention is toward the flare, shoot its eyes with every explosive tip arrow you can. When she jams her head in the trunk to eat you, shoot it with the shotgun to make it retreat. Once it frees its head, throw grenades until it falls over. Then, immediately run over to her and finish her off with a knife through the eye.
Shoot scorpions with a shotgun or cause an explosion next to it to flip it over. You can run up to it and use your knife to kill it. Occasionally the scorpion will jump on you and you will have to stab it in the head.
Whenever you're getting mauled by a dinosaur or insect, sometimes you can defend against it by beating the creature off Turok. However, if you manage to quickly press the correct buttons and hit only a couple or no wrong buttons, there is a chance that Turok will not just push it off but stab the creature to death. This can also happen if the creature mauling Turok has already taken some damage beforehand.
When facing the bigger, tan version of the raptor, go to a place where he can corner you. Then, slowly back up against the wall and you should slightly go up the wall, making it impossible for them to hit you and allowing you to pick them off easily.
When facing enemy soldiers with chainguns, do not attempt to knife them as they are immune and will always mow you down before you get close. Also, do not use the bow with normal arrows as they have very little effect on the chaingunners. However, Tek arrows will hurt them significantly. When using a sniper rifle against them, it is very difficult to get headshot on them. Body shots tend to take more than two hits on the chaingunners.

On one of the "hold your position" missions, set up the mini-gun auto turret to help you while you killing people with the pulse rifle. When you pick it up it sometimes will have more ammunition than when you set it down.
To kill enemies quickly and quietly, use the knife and bow. Do not use weapons that will cause explosions and draw attention such as the Tek arrow. Also, try to kill them in an area where there body will remain hidden after they die to prevent a soldier from finding the body and alerting his comrades.
Use stealth when fighting enemy soldiers as they usually bring in reinforcements and flank your position when they have spotted you. If they bring in reinforcements, it will then draw the attention of nearby dinosaurs and insects, causing them to attack you as well. Try to lure creatures into fighting the enemy soldiers with flares or by shooting dinosaur eggs while hidden.
Use the knife instead of guns when fighting most dinosaurs. This is because the knife is an instant kill and will save you precious ammo in the long run. However, for Dilophosaurs and giant insects, use some type of explosive or specific weapon to stun them or knock them off their feet for a moment before you knife them. Even under the Hard and Inhuman difficulty you should still use the knife on the dinosaurs, although you will die frequently unless you can get the timing done precisely. Since the game checkpoints before most fights, it should not matter.
