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.
Windows version: Moddb.com
This pack was made in order to make downloading these maps as simple as possible and bring content to server creators and mod developers.
