Well it's quite simple really, It's a game mode in which i believe is unique to Garry's mod. The Objective is simple, you're all terrorists, However a select few of you are Traitors, And depending on how many traitors, there are so many detectives (which could be made managable through RTB server prefs.) All TTT is, is a game of deception, And I love playing it on gmod, But let's face it, no one play's TTT on gmod anymore, mainly because all servers that used to be up were all clan hosted, and the clans were a bunch of jerks, more so than not. anywho, Not much to it, But i'd love to see it in Gmod. One thing I forgot to mention, Terrorists get a set amount of credits to buy special equipment, the default is 2 credits, And most equipment cost 1, However more advanced equipment costs more credits, which are obtained through traitorizing (yea that's not a word), In other words, Killing the innocent terrorists, And same thing with detectives, but with detectives, they get credits for Finding clues and scanning bodies and doors and whatnot (and finding Terrorist DNA). My best bet to learn about it is either A.) Play it, Or B.) Youtube
