Well, go to the first level in North Africa.Head up the mountain, make a right, get the health pack and the other one. Then go back to the beggining of the stone wall. Try to jump onto it and keep trying until you do. Go forward walking on the wall and then go onto the mountain. Go up it. DO NOT CLIMB ALL THE WAY UP IT CAUSE YOU WILL FALL OFF!Then go down the side of the mountain torwards the little sand bar. Notice it will not let you back up the mountain. Then go diaganolly up the mountain until you see a gate. Go left so yo can fall onto the little mound next to the gate. Follow the path to the city(communications array)Then go forward after killing the guy and turn right to see a building with a staircase. Be ready to murder all the dudes. You might need to use health packs. After you kill them all, go up the staircase and collect the 2 health packs. Go into the room. Notice all the machine guns are gone.Move on until you can go down the staircase. Go through the gate to the generater. Murder all the guys and notice the generater is gone.Also, notice you can go through some houses. Look around for a staircase. And then notice you are walking on nothing!
