After you've killed the first two dinosaurs in the level, walk down the narrow passageway. When you reach the end turn to your left look up and you'll see a cliff lower than the rest of the cliffs climb up the wall directly underneath the cliff. When you get to the top you'll see a guy with a pulse rifle cannon, a box of shotgun shells. Defeat him, then enter the narrow passageway to get the auto shotgun.

When facing the Campaigner (the final boss), take out your Particle Accelerator and start charging it. As you charge it the Campaigner should stall and stand still. Now fire it at him and change your weapon (the minigun and auto shotgun work well.)

Even though he has a forcefield he'll start laughing as he blocks your attack. This leaves him open for your second attack. Repeat this process for an easy victory.

When you get to the temple with the save point on top, save then look around. Look to your side and you'll see a ten-point Life Force. Walk toward it and you should see a sparkling path. Follow it and you'll find the Grenade Launcher.

Skip Across the Water

it works: 0% | it doesn't work: 100%

Basically, this little trick will allow you to jump on the surface of the water repeatedly to the other side. To do this, fall off the ledge toward the surface of the water, but tap the jump button as you hit the water. You should jump off the water! If you get the timing just right, you can jump right along the surface of the water!
