Some roles like mercenary or vampire could possibly work but stuff like jester or glitch would be a fucking nightmare to make rules for.

I was talking about the main four. Serial Killer, Jester, Survivalist, and Infected. 

Jester would likely be disabled, as with the rules making Jester impossible to play as you can't actually fire. 

So mainly Survivalist, Infected, and Serial Killer. I'm talking about the Original Jenssons Customs Roles.

I know that survivalist is like a discount detective who isn't proven, and Infected is a zombie type, but what is serial killer?

Pretty sure its a t that kills all including other ts(Pretty sure it shows up as a fellow T in the tab menu)

The Serial Killer, although it was bugged at first, is its own role. It fights against all players, has 150 hp, has the knife from GMod Murder, and it's own shop inventory. The old version was bugged as Near said, as it was stuck as a T Role although it was its own role for a while. Jenssons spent a while fixing the role, now it works perfectly. I heard he was working a zombie role, but that's just a rumor.
