Hmm, so you like mystery games huh? Well that's what TTT is, so grab a shotgun, get with a buddy and trust no one, because this is TTT.

First off, What the hell is Trouble in Terrorist Town? Well it is a gmod gamemode that requires counter-strike: Source files. If you have both, you're good to go, just find a server and have fun.

I will now explain the premise of the game, there are 3 groups, traitors, innocents, and detectives. These 3 subgroups are chosen at random at the beginning of a round, Detectives have their rank revealed and can be trusted, but they're the smallest group. Innocents are the most vulnerable and largest group, but can't tell who is who. Traitors can only know who fellow traitors are. They are the 2nd largest group in TTT, they must work together to eliminate the detectives and innocents effectively, without anybody noticing. whichever group is eliminated first (if detectives are eliminated, they are just nonexistent to that point and vice versa) loses the round.

Now then tips for being a traitor:

Don't tell anybody

Act Normal

Falsely accuse innocent players of being traitors

Buy a radar to see everybody alive on the server

Be convincing

Be stealthy

Use Traitor weapons as little as possible, only when the live population decreases dramatically, or you're alone, use them frequently.

Don't kill fellow traitors

Notorious T weapons: Silenced firearms, knife, C4 bomb, Jihad bomb (AKA suicide bomb), and custom weapons depending on servers.

Also as a traitor, some maps may have traps or secret rooms designed specifically for traitors. Such as the infamous 67th way (Beware of the traffic in the streets though)

Also traitors, you have a time limit, time gets added fore each kill. Like in TF2 when a point gets capped.

Tips for being Innocent:

Use your wits

Use your mic frequently

Identify Unidentified bodies

Kill only when being shot at

Resist the urge to shoot everything

Try to be helpful

Stick around detectives or proven innocents.

Don't use fallen Traitor or Detective weapons unless you got permission from a Detective that you're proven.

Weapons laying around the map are the standard weapons for Innocents.

Tips for being a Detective:

Use your wits.

Use your Tools

Figure out who did it

Buy a radar, like the traitors, you can see who is alive on the server with this tool.

Provide health with health stations (be warned, traitors can take health too)

Be a good detective

Don't kill unless shot at, or you have evidence with DNA scanners.

Use the DNA scanner on corpses to figure out who killed them, the only cases with no DNA is if the victim was shot by a sniper, fell to his death or was pushed, was crushed by a heavy object, burnt to death, died from an explosion, or some other cause, also corpses can be burnt by traitors, leaving no evidence behind.

I hope that helped and if you haven't played this game, I highly recommend it, if you have Gmod and CSS or CSS files, play it now! If you don't, buy it off steam. All you need to do is find a TTT server under the gamemodes menu on Gmod.

Good luck and have fun and BTW, everybody is a traitor.
