Doom Builder 64 Enhanced

What Doom Builder 64 Enhanced is
Doom Builder 64 Enhanced is a free Windows editor for creating DOOM 64 maps. It is a fork of Doom Builder 64 intended to update the editor’s source code and add features for mappers. The project lists DOOM 64 Remastered, DOOM 64 EX+, DOOM 64 EX+ Enhanced, and DOOM 64 N64 as supported engines. Its level-editing capabilities include 2D and 3D dimensions and entity placement. Available plugins include a Comments Panel, Copy Paste Sector Props, Stair Sector Builder, Statistics, Tag Range, and Reject Editor. The Reject Editor has a specific caveat: it may crash the first time a new map is saved if the map does not have its own WAD file. The README says it works after loading and saving a map that already has a WAD. Work to update the code to the latest original Doom Builder 2 source is still in progress. To distribute and launch the editor, the project directs users to download a ZIP of binaries from Releases, extract it, and run Builder.exe; there is no traditional installer. Microsoft .NET Framework 3.5 is required. Only building on Windows is tested and officially supported. The project identifies its license as GPL-3.0, and the listed free plan costs nothing.
