CIGWolf (also titled CIG Wolfenstein) is a mod for registered Wolfenstein, made by AReyeP. Finished in 1994 for Wolfenstein v1.1 it was released to a wider audience only in October 2003, but was quickly withdrawn due to possible legal issues.
It takes place at the CIG Facility in Preston (presumably Australia). CIG makes piping systems and components.
Many new graphics were featured. Some were recycled in WolfenDOOM and Spear Resurrection. It includes the Spear Resurrection clone driving a forklift (!) and guards have been substituted with drones and vats.
A long story is included in the download. Withdrawn in 2003 it has not resurfaced in any official shape or form as of yet.
