Duke Nukem 3D is a port of the PC game, released only in Brazil. It was developed in-country by licensed distributor Tectoy in the late '90s for a market where the original Sega Master System and Mega Drive continued to sell well into the 2010s. The game's reduced visuals and performance may have been seen as a necessary compromise to reach the Sega console's large and active install base there.
According to Tectoy president Stefano Arnhold, the port's first-person perspective was adapted from the labyrinth camera used in Phantasy Star for the Master System, which the company had previously localized into Portuguese. This development allowed the game cartridge to omit 3D add-in chips, which would have been prohibitively expensive.
