This is possibly the most highly anticipated game in history, so it's understandable that concerns may be raised about its quality. Thankfully, it manages to live up to all these expectations, delivering an exhilarating experience that will keep one playing for hours and hours on end.
That said, the game is very, very violent. It features multiple ways of killing enemies, most of them involving quite a bit of blood. However, it's nowhere near the level of games like Grand Theft Auto or MadWorld. I believe that most people ages 15 and up will be able to appreciate this game, but that parents should definitely screen it to see if it's right for their child if he's under that age.
