The Departed/ Internal Affairs/ 無間道
All players alignments are "undetermined at the beginning of the game except for two townies and one scum. There would be 12 players.
original set-up as day 1 begins:
-player 1 is town
-player 2 is town and know player 1 is town and player 3 is either mafia or scum. He can pm
player 3 during the daytime.
-player 3 does not know if he is town or scum. He can pm player 2 during the night and player 4 during the day. If player 2 die first he will have the same alignment as player 2. If player 4 dies first he has the alignment opposite of player 4
-player 4 does not know if he is town or scum. He can pm player 3 during the night and player 5 during the day. If player 3 dies first he will have the same alignment as player 3. If player 5 dies first he has the alignment opposite of player 5.
...
-player 11 does not know if he is town or scum. He can pm player 10 during the night and player 12 during the day. If player 10 dies first he will have the same alignment as player 10. If player 12 dies first he has the alignment opposite of player 12.
-player 12 is mafia and knows that player 1 is town. He can pm player 11 during the night.
So there is a chain of dependency that runs from player 2 through to player 12. If a player whose alignment is undetermined dies then his alignment is randomly chosen. All players who know that they are mafia submit a choice for the NK. The target of the NK will be chosen by a clever mechanic that is unknown to all of the players. If no players know that they are mafia, but there are still players with "undetermined" something may or may not happen- town may win, someone may be randomly chosen, the players do not know.
When one of the players in the chain between players 2 and 12 dies, the chain connects again to fill in his place the moment the death scene is posted. So if player 4 is lynched, starting the following night player 5 will be able to PM player 3 and starting the next day player 3 will be able to PM player 5.
The town players will possibly win if all of the mafia are dead, and will definitely win if there are no players of "undetermined" alignment and all of the mafia are dead.
The "undetermined" players have undeterminedwin conditions.
The mafia wins if there are no players of "undetermined" or town alignment left alive.
The players not knowing all of the mechanics is part of the flavor.
