Counter-Wolf 2 is a mod for registered Wolfenstein, made by Ryan King. It was released on May 18, 2004.
Though listed as being a sequel to CounterWolf, it is in fact simply a finished (or partly finished) version of that mod, as Episodes 4 & 5 have been pretty much finished and two new levels appear in the sixth episode. The final level, E6L2 cannot be finished.
Coding changes include new sign-on screen, help art, changed ceiling colors and episode names, menu layout and end level objects. Ammo limit has also been raised.
No further progress was made in the CounterWolf series after this release.
