Is halo appropriate for a fifth grader?
No. Halo and most of the games in the series are rated "M" for Mature. Games with the "M" rating are intended for people 17 years and older. Halo contains a lot of intense violence and mature language. With Halo 4 coming out in a matter of days, the violence and gore is only going to increase. This is a game is not intended for 11-12 years old.
