The Iron Skull
These skulls are simple to get really. You can be on any difficulty but easy. There are two skulls but I don't know if you have to get both of them. The first one is when you come to the first bunker like building. Looking at the bunker the skull will be on the far left on the edge of the rock by the ocean. This next skull is on the very last part where there should be a dam like bridge thing. As you walk along the dam go to the far right and there should be a box or somthing to jump on to. After you get on the box jump up on the window ledge. Then walk left all the way to the end and the skull will be there. There you have it. Oh and I don't think the first skull does anything.
