Tekkoudan is a mod for registered Wolfenstein, made by Ben Blaufarb. It was released on July 15, 2000.
Work commenced in October 1999, initially as an RPG, but this was later changed to a Wolfenstein mod, initially titled Neo Wolf 2 and envisioned as a sequel to that mod.
It features 3 levels and is an unfinished alpha version. Many new graphics are featured, along with many new sounds and a modern atmosphere, including slicker automatic weapons, colored floors and sprites include lap top, traffic cones, syringes and manhole covers. This makes for an urban atmosphere, and as these types of mods were scarce in 2000, many mods over the years took a lot from Tekkoudan.
The mod was never finished but had a dedicated site that was since abandoned. Ben Blaufarb did not release any further projects.
