For over 11 years, Wolf4SDL has been the definitive source port for the classic Wolfenstein 3D experience.

Wolf4SDL retains much of the original gameplay and style of Wolfenstein 3D and Spear of Destiny, while fixing many issues and being able to run on modern systems without the need for DOS emulation.

Originally developed by Ripper, several talented community members have refined and improved the engine over time. The main fork of Wolf4SDL has been maintained by members of the community including AlumiuN, Chris Chokan and most recently AryanWolf3D.
