Originally a remake of the Team Fortress modification for Quake. Team Fortress Classic features over nine character classes - from Medic to Spy to Demolition Man - enlisted in a unique style of online team warfare.
This pack does not just include maps that I have had archived on my hard drive from the past 20 years. I also ported some maps to Opposing Force. Read documentation for more info. I have made a Windows version of this. The Windows version has utilities for modding Half-Life.
