Maybe I had the wrong impression about one thing but I thought that it was possible to be behind a car/wall and lift your gun above your head and shoot for cover fire? Last nigth in the demo, I go caught in a big firefight and I got pinned behind a car. Because the guy shooting me was on a mounted gun, he had an endless supply of ammo. I couldn't lift my head to get a good shot and my team was pinned down also.
