Level 3: Reverse Engineering

Kill the first three guards by having all the commandos run around behind them and shoot them with the pistols. Then go to the other side of the rocks and fire once. When the guard comes to investigate, shoot him and then the next guard who comes to check things out. Use the Green Beret's knife on the guard by the riverside. Next, have the Marine swim down to where the raft is guarded by a lone soldier. Wait unril he walks away, then take off your scuba gear, run up behind him, and kill him with the knife. Move to the corner of the wall where you can't be seen by the single guard who patrols through there. When he begins walking away, run up from behind and knife him. Go back and grab the boat.

Hop back in the water and swim around the fence. Get out next to the stack of cables where you are hidden from the guard to your left (who looks out over the water). Crawl over and kill him with the harpoon or knife and crawl back. Crawl along the fence and kill the two guards by the uniform. Swim around to where you have one guard with his back to you and another patrolling. As soon as the patrolling guard turns away, pop up out of your scuba gear and kill the standing guard with your harpoon gun. From there, sprint over and kill the patrolling guard with your knife. Then, swim over to the far side and take out the lone guard with his back to you.

Go back and pick up the Spy and put him in the boat. Take him over to the set of cables near the water and have him crawl along the fence and use the syringe to kill the guard. Take the uniform and get back to the boat (kill the other guard if you feel like it). If you want, you can swim over to the opposite shore with your Marine and kill the guard along the shore when he gets as far as possible to the bottom-right part of your screen. Do the same with the other river guard, making sure that the guard inside the fence who is watching part of the river does not spot you.

Go back and pick up the Spy, bring him across, and drop him off where you can't be spotted. With his uniform on, let him make his way up to the power source for the electrical fence and have him turn it off. In the meantime, go back and get the Green Beret and the Sapper. Once the spy turns the power off, have the Sapper cut through the wire down where you killed the guard. Have the Green Beret kill the guard inside the fence with his knife. He can also kill the guard patrolling at the far left of the screen, near the first set of explosives, and the guy at the explosives. Let the Sapper grab the first set of explosives. To get the second set you can use the Green Beret to kill him with his knife while the Spy distracts the guard who is looking down. Have the Sapper grab the second set of explosives and cut through the fence close by.

Have the Marine take the Spy and the Green Beret back to the other shore where you first began the mission. Meanwhile, the Sapper should put the first set of explosives next to the bunker overlooking the base of the dam; the charge will destroy the bunker. Once that's done, the Marine can take the Sapper along the far shore to the base of the dam where you can put the second set of explosives to destroy the dam. Have everyone hustle up to the truck to make your getaway.
