NEVADA DESERT

Look to the skies as the level gets underway, and get used to it. You never know what you might see ... There's also rattlers to contend with. They favor the bushes. Off to the right, a snake rests with a rocket. Cross the pool and explore the passage. There's a hallway at the far end that's hard to see from a distance. Push the movable block that you find along the path. Take the ammo and continue up the trail. From the central platform of the two running jumps, you can hang and drop into a barbwire-free zone. To exit the area, you push the block that you pushed just a few moments before. Dealing with the nearby snake first is prudent. Continue along the path, perhaps walking slowly to the right of the metal box, ready to pan the camera up and to the right ... Run and jump from the trail near the metal box to the ledge. Dispose of the snake near the bush, then run and jump to the closest portion of the distant walkway. Run off the end of the path when it dead-ends, and you'll land on a ledge below. Continue along the trail, stepping down to claim a Large Medi Pack, then go back to the trail and run for the rocks. Run, jump, and grab toward the rock pile from the ledge, and continue to the top of the box, wary of the snake. Drop through the hole in the top of the large metal box and you'll fall into a waterway far below. Swim along until you can surface. The large canyon is dominated by the waterfalls at one end. In the opposite direction from the falls, the trail is less glamorous. That's your route. Be ready for a bird attack the first time down the path. There are a couple of harrowing jumps-like around a corner to grab a ledge-but get used to it. This is the big backtrack route. Eventually, you reach a high ledge. You should be on the same level with the rock formation. Run and jump across the canyon to the ledge on the far side. Since this is your first trip, you might as well climb down and get the secret. From the secret, drop into the water below. There's plenty of stuff scattered on the river floor. Don't overlook the waterfall niches. From the water, climb the low red rock near the waterfall. Climb the tall red rock next to that. Run and jump to the slope directly across the canyon. Don't grab! If you just run and jump, you arrive standing up. Time for the big backtrack. Head back around the canyon as you did to find the secret, but this time stick to the upper path. Jump shy of the bush, or you'll step on the snake lurking thereabouts. Don't fall in the hole on the ledge when you jump past the rock. Past the rock and the hole, hang from the ledge and drop to the crack below. Shimmy left. From the ledge at the end of the crack, jump up and grab the underside of the ledge. Swing hand-over-hand to the cliff face. Press up against the cliff, then drop and grab to hold the surface. Climb to the left and up. In the area near the Save Crystal, you can see a big TNT box down below. There are also Flares down there. You need the Detonator Key to set off the charge. Now's a good time to save. Jump to the slope beside the falls, and grab the edge when you slide. Climb down to the ledge below, Follow it along the cliff. From the end of the ledge, jump and grab the tall climbable surface. Climb all the way to the top, and backflip to a flat rock. From the flat rock, jump and grab the slope in between the falls. When you pull up, you'll slide toward a ledge. Jump and grab. Take the ammo, jump to the crack, and shimmy right. When the camera pulls back, drop and jump to backflip across the waterway. Jump the small platforms up the stream. A gigantic waterwheel dominates the cavern. On the left shore, round a boulder to the left and kill a snake. About-face at that point and crawl under the large rock. Back on the shore, there's a small chamber to the left of the waterwheel. Inside is an elevator in the down position. On the elevator is the Detonator for the TNT. Kill the badguy and climb the waterwheel. Follow the sides of the channel to an open area, ready for an air assault. In the water to the right, which is safe, you can swim down to a switch which opens a nearby door. Once you collect the ammo from the small underwater chamber, throw the switch closer to the falling water. As soon as you go inside the underwater tunnel that opens, look for a switch on the dark wall overhead. Pull it. Swim through the tunnel, pulling another more obvious switch, and you'll surface in a hallway. Throwing the switch here activates the waterwheel. On your way back to the waterwheel, check the dry river bed. You can jump to the upper ledge, then back to the river bed. There's a block below that let's you get behind the falls. You can get back to the river bed from one end of that same block. Your ultimate destination is the elevator chamber near the waterwheel. Dispose of the guard and take the Detonator. Now it's time to backtrack once again. Back at the TNT box, notice the boulder that will threaten to ruin the big moment. Use the Detonator and jump to the left. In the blown-up area, climb the ledges. From the highest, large ledge, you can climb to the next area. It's a quick trip around this large area, if you know where you're going. Circle the fence to the left and climb to the narrow, dark passage. At the juncture, jump and grab the upper ledge. There's no need to go down just yet. Swim down in the chamber: there are two switches to pull. One is behind the pillar, the other is in the tunnel. Backtrack to the area near the electrified fence. This time, go down the wide cave opening. Snuff the snakes and throw the switch inside the small building. Return to the narrower passage, and choose the low road at the juncture. Once the guards are dealt with, you can jump from the structure to a box across the fence. Expect trouble as soon as you hit the box across the fence. Remember that nearby lethal current as you fight: best to get out of the narrow area. In the buildings you'll find badguys, a lock, and the Quad Bike. You can ride the Quad to the top of the building (risky) or use the box and grating to climb to the Generator Access pass roof. Backflip when you open the generator room and take decisive action. With the electricity off, open up the main gate-the switch is right beside it. Ride the Quad Bike down into the cave and use the big jump to clear the fence.
