If Duke Nukem Forever's ESRB rating is any indication, the game is pretty darned raunchy.
The ESRB has put up its rating description for Gearbox's Duke Nukem Forever, and boy, is it something. The game is of course rated "M for Mature," with very good reason.
Violence-wise, Duke Nukem Forever seems pretty standard. Players kill aliens with varying types of weapons, like lasers, shotguns, and knives, tearing off their heads and limbs and spraying blood all over the place. Standard for an intensely violent game, anyway.
The silliness with regards to sexual humor also takes Duke Nukem Forever from beyond the realm of E10. The ESRB writes that Duke enters a strip-club level where he can get a lap dance. A mission in this level (**SPOILER ALERT**) has Duke collecting sex toys and pictures of topless women.
Other sequences "strongly imply sexual acts," the ESRB says. One involves two women that "appear to perform fellatio on the central character (e.g., raising their heads from his lap)." There's another where: "Duke moans and leans up against the wall of a bathroom stall (furnished with a hole)." Some of the dialogue includes gems such as: "I have hungry-you have big egg ro' for me, Duke."
So that covers Duke Nukem Forever's sex and violence, but what about toilet humor? Well, the ESRB says there are colon cleansing jokes, Duke can urinate in toilets, and he can also pick up feces and throw it at the walls.
Gearbox was worried that Duke Nukem Forever would be "too crude" for the ESRB, but the organization evidently took the best the game had and survived. I'm not so sure the game will be as well received by the non-gaming world, though perhaps it'll slip through the cracks and never show up in a single "videogames are bad for humanity" newspaper article or television segment. And maybe pigs will learn to fly in addition to policing Duke's world.
Duke Nukem Forever will be released for the PlayStation 3, Xbox 360, and PC on May 3, 2011 in North America, and May 6 everywhere else.
