Duke Nukem 3D Source Ports The Duke Nukem 3D source code was released to the general public in 2003, which led to a number of custom PC ports that kept the same graphics and gameplay while offering some enhancements. These include source ports from EDuke32, JFDuke3D, and nDuke, among others. Some of these source ports even include multiplayer support. Duke Nukem 3D Source Port A Brief History of Duke Nukem Duke Nukem 3D is the third title in the Duke Nukem series of action games. It was developed by 3D Realms and released in 1996 as a shareware release that offered a portion of the game for free. The shareware release included the first episode, titled "L.A. Meltdown," where Duke fights through a deserted Los Angeles. The full version, released shortly after the shareware version, includes two additional chapters, "Lunar Apocalypse" and "Shrapnel City". Duke Nukem 3D marked a major shift in game design, moving from the 2D platform of the first two games to a 3D first-person shooter. Duke Nukem 3D, along with first-person shooters such as Doom and Wolfenstein 3D, represents the dawn of the first-person shooter genre, and are considered classics today. In addition to being immensely popular with gamers, Duke Nukem 3D was critically acclaimed as well for its level design, gameplay, and graphics. Set in the early 21st century, players assume the role of Duke Nukem as they try to fight back an alien invasion. The game consists of a number of levels featuring indoor and outdoor environments that can be completed in a non-linear format. Players guide Duke Nukem through these environments fighting alien enemies as they try to achieve goals and objectives. The environments and levels in Duke Nukem 3D are both destructible and interactive. Players will be able to interact with inanimate objects found throughout the game, such as lights, water, non-player characters (NPCs) and more. Duke Nukem 3D Game Modes Duke Nukem 3D features both a single-player campaign and a multiplayer mode. The single-player mode revolves around the above-mentioned levels and contains a semi-humorous storyline with references to popular films of the time. There are also cameos of popular movie characters (in the form of dead bodies): Indiana Jones, Luke Skywalker, and Snake Plissken, to name a few. Duke Nukem 3D also features a multiplayer game mode. Multiplayer gaming was in its infancy when Duke Nukem 3D was first released, but players were able to connect via modem, LAN, or serial cables. There was also multiplayer support over early gaming networks such as TEN. The multiplayer games took place in the same environments as the single-player version.
