18 years ago today a little shareware game about aliens, strippers, shotgun wielding pig cops and left-field borderline inappropriate comments droped on MS-DOS. Today Duke Nukem 3D turns 18 years young.

To celebrate the birthday of cigarettes and dirty mags an anniversary edition from developer Devolver Digital will introduce cross-platform online multiplayer for the updated Megaton Edition of the game. Check out the video above of the anniversary edition available on Steam.

While the latest Duke Nukem remake didn't fair so well the not-so-dated original is still a wonder to behold. It's like playing a pubescent male, short attention span brain simulator.
