Hey Im on the 3rd level, and Im stuck. basicly I get to the top of the hill, and the cutscene starts and the 2 guys run in the cave. Music comes on and I kill all the people who are running and shooting at me, but after I kill then I enter the cave where the 2 guys ran in, and the way is blocked off. The music is also still going. I searched the whole area for more enemys, but I coudnt find any more. Is my game glitched? I plan to try it again on an easier difficulty and see what heppens. Im currently doing it on hard, and Ive restarted the checkpoint and the level and it still doesnt work. Any help?
