I was playing the level 343 Guilty Spark today and just beside where you begin to head down inside the underground there is a rock which you can jump onto then jump onto the outside of the map. When I was searching around thinking there may be a skull up there I found a Marine who looked just like the one who goes AWOL and starts shooting you. He just stood there looking at a tree. I’m sure this has been found before, but does he serve a purpose?
This is incredibly old. As for a purpose, no purpose.
He was in the original game too. I think hes a placeholder for a cutscene later on
