-induces madness, causing everyone to appear to be traitors
I'm sorry, but what?
That's a fucking awful idea.
First of all, do you even KNOW how TTT works?
EVERY FUCKING PLAYER knows that there are 3 traitors (Out of 16 people) and if everyone looked like a traitor that would be as dumb as shit and extremely obvious.
Not just that, but kill them after 10 secs?
As long as you're taking out the gun to shoot someone and run away, (Since they're going to fucking kill you because EVERYONE MEANS YOU YOU DUMB FUCK) you may as well paint "IM A TRAITOR" on your ass and run around with a splintered up stake in it.
Now if that's not enough, how many fucking bogus kicks and bans do you think would get started? "OMFG HE HACKED MY FUCKING VIEW FUCKING HACKER"
Now not just that, 3 shots? Fucking really? The first thing a good troll would do is shoot the detective, and then once he kills fucking EVERYONE, ban him for the reason "RDMED MORE THAN 3 INNOS FUCKING PRICK"
After that, (Assuming the detective didn't kill you because IT MAKES EVERYONE LOOK LIKE A TRAITOR) you now have to shoot 3 people without them killing you first for ruining their game AND karma.
Now let's assume this: It doesn't make the person who shot it look like a traitor. "OK HE DOESNT LOOK LIKE A TRAITOR AND EVERYONE ELSE DOES." Boom. You're dead.
How about this: You don't lose karma for kills while under the influence of the dart gun. Everyone would message their traitor friends on steam, have them shoot them with a dart gun, and murder EVERYONE. And get away with it with no consequences whatsoever.
But anyway, I needed to vent, that kinda helped.
