Pacing lizard at title screen
Go to the "Cheats" menu and watch the "Art Gallery" presentation. After "The Turok Team" picture, it ends and begins to cycle again. Return to the first main menu and wait for about five minutes. From the left, a small green lizard will walk along the bottom of your screen, with a picket sign that reads "Lost Land or Bust!!!". When he reaches the right side of the screen, he will turn around and walk the other way, revealing the other side of the sign which reads "Start the Game!". He will look over at you a couple of times, but mainly stares at the ground.
Nuke in single player mode
In Chapter 8, "Arena", defeat the Steracosaur Boss. After doing this, the force field around the middle pillar will drop. Climb to the top of the pillar to get both the Nuke Attachment (for the Rocket Launcher) and a Nuke. You will now be able to fire the Nuke only twice (the Nuke Attachment has a Nuke already in it). There are no more Nukes past Chapter 8. Also, the "All weapons" and "Unlimited ammunition" cheats do not work for the Nuke.
Nuke in multi-player mode
The Nuke can be found in three multiplayer levels: Tears Of Horatio, Withering Heights, and Dino-Depot. Note: Do not have the "Unlimited Ammo" option in the multi-player options menu activated or the Nuke will not appear. You can still use the "Unlimited Ammo" cheat in the cheat menu and get the Nuke. The "Unlimited Ammo" cheat does not give you unlimited Nukes. The Nuke will respawn after a period of time.
Tears of Horatio: Go up either path, up the cliff, until you reach a big metal platform with three holes in it. Turn around and you will face a huge rock pillar. A Swarm Bore canister will be at the foot of the pillar. Directly above the Swarm Bore canister is the Nuke, floating in the air. You must have the Jump Boots to get it.
Invincible Raptors in multi-player mode
Tears Of Horiatio: Get the nuke and stay up there. If your friend approaches, shoot the nuke directly at the ground below you and do not move. It will not touch you, but will kill anyone around you. There is also a good hiding spot in at the end of that level, where there are cannons. Go on one of the side cannons and go to the very end. Then, turn around and quickly hit back and then forward. You should get stuck. Try jumping a lot until you are in it. If you do not go in, drop a little bit farther and try again. This place is a good hiding spot from trackers like the plasma cannon.
Withering Heights: Do not flip the switch as described above. If you do this and jump to the center platform, you will be killed by a trap cage. Instead, just jump out the window above the disagreeing trampoline and it will appear for you.
Withering Heights: It is small but easy to get around because of the trampolines. The nuke is in the center. You can get it and aim it directly down at where you stand for and instant kill for all around.
Dino Depot: The Nuke can be found on the top of the yellow box car. You must have the Jump Boots to reach it.
Play in the Regeneres Arena level in multi-player mode. Go to the big door with the Jump Boots in it. Get the Jump Boots. Back up slightly and jump up on to either of the little ledges on the sides of the door. Then, jump up to the gap in the wall higher up. Next, go all the way to the right. You will see a little button-like object with a picture of a person cut in half and a raptor next to him. Either shoot or hit it with your War Club. When you do this, stay up on the gap. Look below to see that the big door and the other three doors will open. Raptors will appear from them, and you cannot kill them. However, they will go after the other players. To make them go away, wait until they go back in the doors. This is useful, as the raptors kill the other players and they lose kills as if they killed themselves.
To kill Bruckner, the last Boss in the game, run a safe distance from him. Line him up with a tree so that it is in front and Brucker behind. When Bruckner gets close to the tree, shoot it onto him. Note: The tree takes more hits than usual to take down. It should kill Bruckner in one hit. This also has the same affect on other enemies.
Kill enemies with one hit from battle ax
Note: This trick does not work on Raptors, Purrlin, and Captain Bruckner. Have the battle ax ready. Hold [Fire] until Tal'Set turns the ax around and puts it behind him. Then, aim for the enemy's head (you might have to jump) and release. It helps to have the invisibility cheat enabled so that they stand still. If you miss but still hit them, try hitting them one more time.
Chapter 1: Frogs and lizards
There are frogs and lizards on the ground in certain areas, usually near the water. Approach one and hit it with the war club. It will burst into large chunks of meat.
Chapter 2: Surprised guide
During the second scene of the chapter is a Brachiosaur that is relieving itself. There is also a Brachiosaur immediately before this one. You will see it behind the second ancient structure as you exit the cave. Fly under the Brachiosaur's legs and you will surprise your female guide.
Chapter 5: Rescue The Wise Father level
You can wipe out all The slegs and the Jailer without leaving the room that leads you into the circular prison room. Best of all, you can have the really big Slegs do some of the dirty work for you. First, get as heavily armed as possibly by breaking all the crates and gathering anything you can use before hitting the switch to open the door. Weapons of choice here are both the explosive arrows and rocket launcher and grenades. Use them in that order if possible. You will need the grenades later in a key point. With luck, you started this level healthy and did not need to get the large med-kit at the start. Being able to return and use it is a big bonus. Begin your assault without entering the big prison area. After you strike your first blow, fall back into the room and wait for them to come to you. Hold them back by taking them out in the hallway. You need to survive up to the fifth wave. Next, head back into the tunnels. As you arrive at the first room with the grated floor above, you will probably see two big Slegs. Leave them and wait for the gigantic Sleg to appear. Once he appears, he will proceed to squash the other Slegs. Wait for the other Slegs to arrive. After the other Slegs arrive, they will all just stand there (including the gigantic Sleg). As you move, the giant Sleg will follow. Guide him to the other Slegs and they too will be squashed. Continue this until the giant Sleg refuses to play anymore. Them take out your spiked grenades. Stick them under the feet of any that remain, then back off and watch them go down. When you get to the Jailer, it will require about five grenades to kill. Return to the beginning to replenish on grenades and health if needed. Once the Jailer is gone, you have the entire prison area's stash of weapons at your disposal.
Chapter 8: Arena level: Extra ammunition
When you begin this section, you start in a room with a large door both in back and in front of you. Also, in front of you is a supply of ammunition. Normally when you leave this room, the door will close behind you and will not re-open. Use the following trick to keep it open. After sniping everybody you can from this room, turn around and face the back of the room. Then, look all the way up. As you are looking up, walk backwards so you can see the front (open) door. Continue to walk just out the door until you see the door begin to close. Wait until it is half way down and go back into the room. The door will re-open. It should now be stuck open. If not, then repeat the process until it sticks. You now have the remaining ammunition at your disposal.
When you see a raptor or an alligator, you can save ammunition by using the war club. Hold [Shoot] and your character will hold the club back. When you release it, he will use the spiked side of the club, which can kill alligators and raptors in one hit.
Better aim with weapons without scopes
Equip a weapon with a scope (Tek Bow recommended). Aim at whatever you are trying to shoot with the scope. Then, switch to a more powerful weapon without a scope and fire. The crosshairs will not move and you will hit the target.
Killing underwater alligators
Use the pistol. It will shoot things that are underwater when you are not.
Glitch: Invincible Sleg
In the first part of Chapter 4 (Infiltration), go to the place where there are people being hanged. Make sure the alarm is not active. Wait for the two Slegs that are shooting the people to start walking towards them. Get behind the machine gun, and while the Sleg on the right is pressing a button and making a beeping sound, shoot him. You will probably blow his leg off, but instead of falling on the ground, he just stands there. He will not die, even if you keep shooting him.
Glitch: Crawling Sleg
The following trick requires a Dark Matter Cube. Go to a door with Slegs inside. Throw the Dark Matter Cube at the door. It will suck them in. The door will also open. You will see one or two Slegs still alive, but they are leaning forward and appear as if they are crawling. Note: This may require several attempts.
Glitch: Floating raptor in multi-player mode
Chose a raptor in multi-player mode. Go to the first place seen when choosing a destination. Go underwater and press [X] to see yourself, then start walking. Next, make yourself appear to be walking at the bottom. Then, hold [A]. When you are at the top of the water, keep [A] held. You will see yourself begin to float up to the sky. You will fall back down if you hear yourself getting out of the water and will still drown sometimes.
Choose either of the raptors in multi-player mode and go to the first level at the level selection screen. Go to the center of the stage and enter the water. Change from first person view to third person view (where you can see the entire raptor) then press [Jump]. You should start flying out of the water. Note: The game still considers you in the water, and you will start drowning after awhile if you do not change views.
Glitch: Bleeding walls in multi-player mode
Set up your multi-player screen as desired. Choose one of the raptors as your character. During game play, sidestep until you get to a wall. Turn the raptor until his head appears to be in the wall. Press [R] and watch him eat up the wall.
Glitch: Chapter 3: Climb walls
When the dinosaur Rex first appears and the door behind locks, begin walking toward the walls. Continue and if you alert the dinosaur, kill him. Move on the tall grass until you see something that resembles a ramp. Walk toward it. If done correctly, you will climb the wall and reach the other side. The other side has a black fall. If you fall, there is no death. You will continue to fall forever.
Glitch: Orb of Destruction
On the second part of Chapter 4, throw a Dark Matter Cube and quickly pause game play. If done fast enough, it will be paused either just when it hits the ground, or as it is leaving his hand. Resume the game and he will have nothing in his hand. If you throw another cube, it will reappear. If you switch modes (go to the secondary mode), it will appear as if you have an orb in your hand.
