Duke Nukem 3D (ESRB ratings: M) is an extremely controversial first-person shooter video game that contains adult material such as violence, explicit nudity, pornography and foul language. The player controls Duke Nukem, a reckless man who fights a horde of invading aliens across urban settings, deserts, canyons, military bases or even space stations.
The game was banned in Brazil following a shooting incident reminiscent of the events occurring early in the game.
