The role is a role called "The Gambler", and is a test role according to arachnidsGrip.
I get given the faction of a random person every night. However, there is a 1 in 5 chance that the faction is the opposite of what I'm told (e.g, an innocent shows up as Mafia, or vice versa). Everytime the report comes back as Mafia, I must go "all-in". I have to vote for them when I go all-in, per the rules of the role. The reports only ever say faction, not special roles.
In addition, every night I have a 1 in (the amount of people left in-game) to die by heart attack. If I found a "Mafia" the previous night (thus having to go "all-in", forcing me to vote for them), and they are not killed the next day after the night I found them, I have a 1 in 2 chance to die that night.
In addition, if the report should be of Marlon Olives, it has a 50:50 chance they report as either Innocent or Mafia. Anyone persuaded by Olives will still have there original faction be the base for the report.
That's basically what the PM said.
