Lately, I've been seeing several posts as to this game being broken. People claim that the enemy always knows where they are or that somehow their position is given away. This video explains a lot. It might not have to do with what was stated, but the video clearly shows how IW is an incompetent game developer.http://www.youtube.com/watch?v=Fb3dcFppVbg
Who cares. I've only seen someone use a MG4 in MW2 once & that person was me.
You clearly seem to be missing the point.
Seriously, this seems like one of the easier problems to patch anyway. Besides, I don't use LMGs and the only pistol I use is the Magnum. So yeah, not a huge problem but definately a really stupid mistake.
