Forks / sourceports

Since the first release of Doom Builder there has been great enthousiasm from other community members in continuous development and addition of more advanced features specialized to certain Doom sourceports (forks). One such branch (Doom Builder X) focuses on continuous improvements while keeping the editor in its classic fashion and generic for all Doom soureceports. Another branch (Ultimate Doom Builder) has completely specialized the editor for the GZDoom sourceport and has added tools to editor special GZDoom features such as dynamic lighting and 3D floors. Similary, the Doom Builder 64 branch has added features specific to the Doom 64 game.

Doom, that shooter from 1993

Despite the age of this game, it is still very popular and the most well known first person shooter. Doom has a large community of players, map authors and even mod authors. Making maps for this game is relatively simple and yet it allows for a great gameplay experience. Especially with the addition of scripting in the maps, it allows for interesting puzzles that rival even todays next-gen games! The community has spawned several new Doom engines that have remarkable new features to play around with in your map (and you can use those in Doom Builder!).
