Duke Nukem 3D

Port Duke Nukem 3D for Sega Mega Drive/Genesis is a simplified version of the original game, featuring only nine levels based on the "Lunar Apocalypse" episode. Instead of directly porting the original maps, this version introduces new levels with a simple design and 90-degree angle restrictions, making them similar to those in Wolfenstein 3D. Textures, sprites, and sounds were taken from the PC version but with noticeable quality degradation. Despite these simplifications, the project is technically impressive for a 16-bit console and remains one of the most intriguing adaptations of Duke Nukem 3D.

The game was released exclusively in Brazil in 1998 by the local distributor Tec Toy. Its legal status remained unclear for a long time: 3D Realms denied authorizing its release, while Tec Toy claimed to have obtained a license through GT Interactive for limited distribution in Brazil. However, GT Interactive ceased to exist in 1999, and the issue was never fully resolved. Later, in 2015, another publisher (Piko Interactive) claimed to have legally re-released the game worldwide, but its legal status remains unclear.
