Ok this game is as easy as first person shooters get. This is a great game. its mild on violence. Of course it is violent, it is a shooter for gods sake!
I'm one of those "mean" moms who won't let my 9 year old play Call of Duty or Halo and other bloody, violent, rated M games. So this one is a pretty good shooting game that he thought was cool, and is still pretty rough. My 6 year old plays it too. Does have lots of shooting, things blowing up, and some bad language (not too bad though). It is a good compromise.
