What is Trouble in Terrorist Town?
Trouble in Terrorist Town (TTT) is a gamemode included with Garry's Mod. The game is about a group of "terrorists" who have traitors among them, out to kill everyone who's not a traitor.

A small number of players is selected as Traitors, who have to kill all the Innocent players (ie. the rest of the players). Those innocents know they are in the majority, but they do not know who is Traitor and who is not.

The Traitors must use the element of surprise and their special equipment, if they are to succeed. The Innocent just have to survive, which means finding out who the Traitors are and killing them before they kill you. Of course everyone is holding a big gun, and everyone looks suspicious...

For the Innocent, knowledge is power: who is acting strangely? Who can be linked to evidence found on corpses? Who is still alive, even?

How do I play?
Follow/check these steps:

You need to have Garry's Mod (GMod) installed on Steam.

You need Counter-Strike: Source installed. (or the textures downloaded)

Then, all you need to do is join a server running TTT, and everything you need will be automatically downloaded.

You can find TTT servers in your GMod server browser by checking for servers that show "Trouble in Terrorist Town" or "terrortown" as their game, so sort on the "Game" column and scroll down.
