LZWOLF
LZWolf is a fork of Blzut3's ECWolf project, combining Wolf4SDL with the philosophies of projects like ZDoom to create a mod-friendly source port for Wolf3D games. In addition, LZWolf adds extra features popular in the Wolf3D modding community to extend it's usability as an engine for creating games.
LZWolf exists in tandem with ECWolf, with the goal of eventually being compatible with all games built on the engine (Including the Blake Stone games, Corridor 7, etc).
Unfortunately, LZWolf's development has been discontinued as of the 5th of March, 2023. The engine is still a fantastic source port for the building of mods, with a lot of cool features to take advantage of, but will not be following ECWolf to a 1.4 release.
