Parents should teach their children to flee this game like they would a severed cow's head infected with anthrax. I'm not sure how the publishers managed to avoid the ESRB's AO rating, but should there ever be another sequel, I'm sure that the vile and pornographic details of the deal will be mentioned in it.
Fans of the first game should check it out, as it is the logical extension into three dimensions of everything that game offered.
