Mapster32

What Mapster32 is

Mapster32 is a free editor for creating Duke Nukem 3D maps in .MAP files, included with EDuke32. It is part of the EDuke32 project and is described as an advanced successor to the original BUILD Editor shipped with the game. Its 2D mode handles map layout and object placement, while 3D mode lets you edit textures, heights, and shading. The editor can also be used to make levels for NAM, WWII GI, Redneck Rampage, and other games. For scripting, it supports a language derived from CON; scripts can be loaded as .m32 files or entered through the editor console. Mapster32 can check loaded maps for corruption and attempt repairs in some cases, though serious corruption may need manual expert attention. It is available for Windows, Linux, and macOS. The listed plan is free, included with EDuke32.

Who it suits

Mapster32 suits people creating Duke Nukem 3D maps or levels for the other named games. Its 2D and 3D modes, scripting support, and map checks address different parts of level editing.
