Team Fortress 2

Team Fortress 2 is a multiplayer team-based first-person shooter, developed by Valve Corporation as part of the game compilation The Orange Box.

The game was announced in 1998 as a sequel to the original Team Fortress mod for Quake, but has since been through various concepts and designs. In 1999, the game appeared to be deviating from the original Team Fortress (and Valve's own Team Fortress Classic, a mod for Half-Life) by heading toward a more realistic and militaristic style of gameplay, but the design metamorphosed further over the game's nine-year development. The final rendition of Team Fortress 2 bears more resemblance to the original Team Fortress and Team Fortress Classic games, and sports a cartoon-like visual style, based on the art of J. C. Leyendecker[4] following a popular trend in recent CGI films (in particular, films recently made by Pixar/Disney, such as The Incredibles).

The lack of information or apparent progress for six years of the game's development caused it to be labeled as vaporware, and it was regularly featured in Wired News' annual vaporware list among other ignominies.[5] The game was officially released on October 10, 2007.
