Team Fortress Series - Wiki

Team Fortress is a series of team- and class-based multiplayer online first person shooter games, designed by Robin Walker and later developed by Valve. The series places a high emphasis on teamwork and coöperation to complete objectives by two competing teams of players selected from nine classes, each fulfilling a different role in the team's ranks.

Released in August 1996, Team Fortress is a game mod based on id Software's Quake engine. The first iteration of Team Fortress, also known as Quake World Team Fortress (QWTF) or Quake Team Fortress (QTF), was designed and written by Robin Walker, John Cook, and Ian Caughley. An update to the game was released in December 1996, which was instead based on the QuakeWorld engine.

Team Fortress Classic

Team Fortress Classic (TFC), also known as Team Fortress 1.5, is a title in the Team Fortress series of games.
Team Fortress Classic is a class- and team-based multiplayer online first-person shooter video game developed by Valve and published by Sierra Studios. A port of the Team Fortress mod for Quake/QuakeWorld, Team Fortress Classic was originally released for Windows on April 1, 1999 as a mod for Half-Life and based on the Half-Life 1 Engine (Gold Source Engine). A standalone version was later released on January 16, 2003. The development of Team Fortress Classic was led by John Cook and Robin Walker, two of the three designers from Team Fortress.

The game itself involves a number of teams, each with access to ten classes, competing in a variety of modes such as Capture the Flag, Control Point, and Escort. In June 2000, the game underwent a significant upgrade, adding new player character models and game modes. As of 2003, the game was one of the ten most played Half-Life mods according to GameSpy.[1] Today, as with its predecessor, Quake Team Fortress, it is not very active, and as such, there are few servers with humans on them, and bots prosper in the majority of servers. Your server browser can pick up at most 100 or more servers.

Team Fortress Classic revolves around two or more teams competing in a variety of game modes with players typically selecting one of ten classes. Players usually have the choice of two equal teams, Red and Blue, although certain game modes allow for more than two teams with access to different classes. The way a player acts in a game is defined by which class they select, with each class having their own strengths and weaknesses. As such, Team Fortress Classic relies heavily on teamwork between players of different classes.

Team Fortress 2

Team Fortress 2 is a team-based multiplayer first person shooter developed by Valve Software as part of the game bundle The Orange Box. It was first released for Microsoft Windows, Xbox 360, and PlayStation 3 on October 10, 2007. Following suit, it was released as a standalone title on April 9, 2008, and on June 10, 2010, Team Fortress 2 was released for Mac OS X. The PC and OS X versions of Team Fortress 2 adopted a "Free to Play" model on June 23, 2011 with all revenue being generated from micro transactions in the In-game Store. After several months of closed beta, Team Fortress 2 was finally released for Linux operating systems on February 14, 2013.
The game was first announced in 1998 as a sequel to the original Team Fortress mod for Quake, but has since been through various concept and design periods. In 1999, the game appeared to be abandoning the art styles of the original Team Fortress Classic by transitioning toward a more realistic and militaristic style of gameplay. However, the design continued evolving over the game's nine-year development period and game engine switch. The final art style rendition of Team Fortress 2 resembles that of the original Team Fortress and Team Fortress Classic games, and also features a cartoon-like visual style based on the art of Dean Cornwell, J. C. Leyendecker, and Norman Rockwell. Team Fortress 2 follows a popular trend in recent CGI films, in particular, films recently made by Pixar Animation Studios, such as The Incredibles.

The absence of media information or apparent development progress for six years of the game's development caused it to be labeled as vaporware, and it was regularly featured in the Wired News' annual vaporware list, among gaming news outlets. Since its release, however, the game has received critical acclaim and several awards.
