Admittedly, I'm a bit late to the party as this mod was released on 5 December, but nevertheless here's a post about the new release by Thomas Weiling: Frantic Passages. Seventeen new levels punctuated with rudimentary features and quite a few new graphics, this new mod by one of the best mappers out there is a must play for every DieHard Wolfer out there. You can download it right HERE.
Enjoy, my fellow Wolfers! :)
