Duke Nukem 3D, a personal computer classic title released in early 1996, featured pseudo 3D effects, a gritty foul mouth protagonist facing off against college humor styled enemies and levels. Tectoy released a Sega Mega Drive (Sega Genesis in North America) version of Duke Nukem 3D that was only available in Brazil in 1998. Nearly 20 years later, Piko Interactive has secured the rights to Duke Nukem 3D on the Sega Genesis for world wide release. Duke Nukem 3D will feature a proper box, cartridge and manual when it begins shipping.
