Has anyone played this lost chapter of the Team Fortress franchise? For those who don't know, Fortress Forever is a Half-Life 2 mod that uses the Source engine. The game is based on Team Fortress Classic, but has been created entirely from scratch by the Fortress Forever development team. The intended scope of Fortress Forever is to please older Team Fortress Classic fans, while at the same time creating a game enjoyable enough to players new to Team Fortress styled games. It was originally released in 2007 (same year as TF2) and now after months of being stuck in development hell, it's been released as a free to play game on Steam.
