Jurassic Park Part 2: The Chaos Continues/T-Rex Carnage

This level is very easy and linear. There are no humans to worry about. Use the cattle prod. Keep going right and enter each "door" as you come across it. The only trouble is at the end. You will eventually reach a point where there are no enemies, only a door a few yards to the right. This is your signal that you're about to fight the T-Rex. Switch to the shotgun and enter. You will hear it roar and you'll see a car. Jump on it. Stay on the left side of the car, the side closer to the T-Rex. Hold down the fire button. If you don't have a lot of health, duck the bullets that Biosyn are shooting at you, but don't stop firing. (If you're playing on the hard difficulty setting, you may want to dodge the bullets even with moderate health.) Your aim is not to kill the T-Rex, which you can't do now, but just to keep it at bay. After the shotgun rounds run out, it'll switch to the machine gun. Keep firing. After those run out, it'll switch to the rifle. This will not be effective enough and you should switch to tranquilizer darts (either bazooka or machine gun). Assuming you had started with the full 20 shotgun shells and 200 machine gun bullets, you'll about ten seconds, give or take, after switching to tranquilizers, before you have to jump on a vine to avoid falling into a huge pit. Listen to the music rising to its climax, and keep your eyes on the ground. Don't stop firing, just watch the ground. As soon as it gives out, jump diagonally to the right. You'll grab a vine and hear the T-Rex roaring behind you. Just go over to the right, jump down from the vines, and the mission will be over.
