Make your way into the control room and use the switch to raise the elevator, then get on the elevator and jump onto the center platform. You'll have to jump and duck under a bunch, then in the large room, find the elevator platform against the far wall and break the box on it so it won't trip a laser when the elevator is raised. Turn left and find the big gaping hole in the roof, and jump down.įollow the scientist's advice: be very careful! You can't touch any of the tripmines in this area or you'll nuke the whole place. When you get to a minefield, throw grenades or shoot your M4/pistol to clear your path.īlow up the barrels to turn off the power, then climb up the tipped tower onto the roof. Through the next gate is a large building which you'll have to circle around to the right. Use whatever tactics work for you.Īround the corner is a stationary tank which doesn't provide much of a threat unless you stand still for too long in its line of fire.Īfter opening the gate, you'll encounter another tank-type thing which you'll have to dodge using the boxes and ledges. Inside you'll find a new rocket launcher, which you can test out on another Apache helicopter which is hovering outside.Īfter climbing up all the ladders and navigating the pipes you'll come out in another great soldier firefight. Slide down the big pipes to get down part of the cliff, and work your way right until you come to a cave. Long-range crossbow sniping does wonders here. Be careful where you step, and watch out for soldiers and sentry guns that can pick you off quite efficiently.

Spin it and then drop down the newly opened storm drain.Īt the end of the pipe you'll notice that there isn't much ground to work with. Watch out for sand-burrowing headcrabs and, more importantly, buried landmines, which will end your adventure very quickly.Ĭreep around the perimeter of the minefield and find the red wheel. In fact, you don't even need to go there - find the other passageway between the rocks. There's another tentacle monster in the next area but you can ignore it if you stay out of range. Be careful, though, since there's another Apache circling around waiting for you. Then climb up the ladder to the top of the building. Run along the canyon and climb up the ladder and through the pipes. (I still don't understand how Gordon slides through the dam, but otherwise it doesn't spill a drop.) Swim down near the bottom of the dam and spin the red wheel to open up the gates so you can pass through.
