Duke Nukem is a game, maybe even a good one, for mature people (13+ or even 18+). It contains a lot of pornography, sex, violence, blood, shooting, and the overall reckless killing of innocent animals and human beings. Some of these include prostitutes and Pig Men (the enemies in the game). They try to portray Duke Nukem as a rogue cop but he really comes off as a cold blooded killer. With an arsenal of many different weapons he kills whoever he wants whenever he wants to.

This game is rated is rated teen (17+). This is very wrong. They rate the nudity at a level 1 (weakest). It should be rated at a 4 (highest). There are women in the game that take their their clothes off for you if you give them money. It is also very bloody and violent. Duke also uses adult language throughout the game, but, unlike the other categories, this is the lowest.
