Remember how we promised that Duke Nukem: Forever would be working overtime to earn that Mature 17+ rating from the ESRB? This new trailer lives up to the challenge: it's got violence, gore, violence, gore, gore, monster trucks, gore, and boobies.

Hey, did we mention that this trailer is NOT SAFE FOR WORK? 'Cause it's NOT SAFE FOR WORK.

You've been warned.

Duke Nukem: Forever comes out for the Playstation 3, Xbox 360, and PC on May 3 June 10 June 14.
