I have a boy who is fourteen and he asked me to if he could have this game so that he could play it. I dont normally let my child play rated "M" games, but after I checked many sites before I said OK to him, I was able to conclude that it is a violent game, but no more violent than Halo (which I also checked out before I let him buy). There is blood, but not in excessive and extreme amounts and of course the small dosage of profanity. The bottom line is that it is rated "M" for a reason, and I think that the proper age to play this game is at least 14 yrs old. Do not let pre-teens or children play the game though. Just like the review before this says only rated "T" ages and up.
