If anyone is wondering why I chose what I did for the title, it is because it is getting really old when parents immediately crack down when they hear about the M rating. I don't have the game but have watched the entire campaign and played multiplayer with my friend. It has violence, sure, but it is a shooter. The noises made by the aliens when they go down are nonexsistent and the blood is a little, and is blue, maybe yellow, and green. Parents often don't think their kids can handle the violence but I think that if you sit down and have a talk about death, they will understand that killing things unless you are hunting or in the military is usually not okay at all. Parents also need to know that you are killing aliens in the campaign, not humans. These aliens are intent on wiping Earth out of the solar system and destroying the human race. The master chief seems like a machine but he, in fact, does have a heart and when Cortana, an artificial intelligence that chief has been sharing his brain with for 8 years, starts to die, he refuses to continue the mission and instead wants to return to Earth. The morals in this game are staggering. The chief isn't killing to save Earth, he's risking his life to save Earth, and he is also risking his life to save Cortana. Speaking of her, Cortana does appear as a nude woman in holographic form, with blue strips of moving data across her body. I think that any mature kid should have no problem with this. In online mode, open voice chat is available and players are free to say whatever they want. If you can't find the switch to turn this off then just mute the TV. I think that this is a great game with good graphics, morals, and very little violence.
