-After the boat crashes, call in an air strike on the corresponding location. Run up to the beach and move to the right to find a small puddle at the right side of the beach. Stand in it briefly, then move towards the middle of the beach to find a smaller puddle. Stand in that puddle briefly, then move towards the far left side of the beach. Stand briefly in the puddle in the barb wire. After a few seconds, the screen will shake and you will hear strange voices before four lion statues rise out of the ground with alien ray guns in their mouths.
-If you just stand in the last puddle and not the others, you will still hear the weird voices and get the ray guns.
