Strategy Informer  

Fortress Forever is a Source mod inspired by the earlier versions of the Team Fortress series (Team Fortress Classic and QuakeWorld Team Fortress). Fortress Forever should please those who have stuck with or been a part of QWTF and TFC over the years while at the same time doing more for new TF players than any prior Fortress attempt.

Fortress Forever is completely free and only requires a Steam account with Source SDK Base 2006 installed.
