If I'm not mistaken. The ESRB or Entertainment Software Rating Board have given a mature rating for Halo 1 or 2, because of the way the Flood (alien fungus like enemy species) takes over a human being. They felt it was too disturbing. So, i think they toned it down in Halo 3 or have compromised by reducing the degree of violence occurring. Such as reducing blood (splash) and gore. So, they got a different or better child friendly rating... I might be wrong on this.
What it feels like to be infected by the Flood
