S-Blaster 3D is a mod for registered Wolfenstein, made by NME Software. A 40-level version dubbed Beta 2 was released on November 28, 2004.
It features many coding changes and a more modern-type setting. Mapping is quite extensive, though all actor frames were not finished. Decor and textures make for a unique atmosphere.
Though the project was rebooted in January and September 2005, and a new screenshot was posted, the November 2004 Beta 2 remains the final version.
