Team Fortress Classic is a first-person shooter game developed by Valve and published by Sierra Studios.

It was originally released in April 1999 for Windows, and is based on Team Fortress, a mod for the 1996 game Quake.

In 2000, Valve released a standalone version, Team Fortress 1.5, with new character models, maps and other features.

This differentiation between classes makes for rock-paper-scissors-esque gameplay that requires teammates to work together in order to effectively achieve the objective.

In Team Fortress Classic, a server can hold up to 32 players simultaneously, and matches can be played in a number of game modes, each featuring different objectives.

[2] In Team Fortress Classic, the player can choose to play as one of nine classes: the Scout, Sniper, Soldier, Demoman, Medic, Heavy Weapons Guy, Pyro, Spy, or Engineer.

[3] In Escort game modes, a player may also choose to play as the Civilian class, which is armed only with an umbrella, no armor, and very little health.

[17] The update added "new sounds and weapons, enhanced graphics, new models for classes and weapons, new maps from popular mapmakers, an updated user interface that makes finding and joining games easy and intuitive, and a new in-game Command Menu Interface".

"[25] PC Gamer US named Team Fortress Classic the best multiplayer game of 1999, and wrote that it was "more fun and more addictive than any other multiplayer-only title released in 1999, and didn't cost owners of Half-Life a single penny".

[34] A catch-up comic released on the TF2 website released for free comic book day described Team Fortress Classic as being set in an alternate 1930, and that the game takes place during the Gravel Wars era of the timeline, along with the fact that the Classic engineer is the father of the engineer in Team Fortress 2.
