Setup:
Pre-game, the mod will PM the players telling them if they are Resistance (town) or Spies (scum). See below for the number of spies for particular game sizes.
The Spies may not privately communicate.
(this is important)
Day phase:
The game is played in 5 rounds (day phases). During each round, the players will vote on a team of players that they want to go on the "Mission" (the mission is just flavour). Each round requires a different number of players for the Mission, ranging from 2 to 5, depending on the number of players.
Voting:
Votes will be cast and counted like in a mafia game. On a day requiring a 2-person team, for example, one might
VOTE: Mathdino & northsidegal. When a simple majority is reached on a particular team, the thread will be locked and that day's team will "go on the Mission".
Night:
During this Mission (night phase), each player must PM the mod whether they want to pass the Mission, or sabotage it. Unless otherwise indicated, a mission requires every player on its team to "pass" in order to win.
If the Mission succeeds, the Resistance gain a point. If the Mission is sabotaged, the Spies gain a point. The next round then begins.
In the morning, the number of players who chose to sabotage is publicised.
Miscellaneous:
If the deadline (up to the moderator, I use 1 week) is reached on a round without reaching a majority, the Spies automatically gain a point, the Mission is skipped, and the next round begins.
All standard rules of mafia apply. While modding, I will be using my standard ruleset.
