Civilian

From TF2 Wiki

Information

As of December 20, 2007 you can no longer join this class

The Civilian is the hidden tenth class of Team Fortress 2. He can be selected by typing join_class civilian into the console upon joining a game. He uses the Scout's model frozen in a neutral standing position, most likely a placeholder. He has very low health (the lowest of any class), and possesses no weapons or form of attack. He also lacks both voice commands and taunts and uses generic speech files when he is wounded or killed. Civilians possess no animations except the ragdoll/gibbing effect upon dying and so appear to glide along the ground when moving.

The existence of the Civilian class seems to indicate that Valve either had planned an updated version of the VIP escort maps from Team Fortress Classic, or plans to add this type of map into the game in future patches. Alternatively, the class may have been included in the game files so that independent modders could add this feature.
