Surface tension helicopter not appearing?

Just purchased this and great job love the remake.
But I have a problem once you cleared out the storage facility as you come out you are supposed to be met by a helicopter you take it out and can move on to the right but there is a large bolder which can not be passed so I guess the chopper blows that up but I can not move forward as no chopper appears??? reloaded game didn’t help. can you use NoClip to get pass the bolder and no chopper problem and move on if so how to use no clip as that is not working either! with cheats enabled thanks for any help anyone can suggest.
