Show me your game design ideas for a Mafia game, /v/.
So far here's what I played.
Flee the Facility - A 5 player game where 1 is the killer and you have to hack 5 computers. The killer is not hidden among the players. He who knocks everyone and puts them in cryo pods to freeze. The players may try to go and rescue each other. There's 2 exits, the computers reveal your location if you don't do a quick timed event, the computers and cryo pods change location. There's these tiny holes in walls the players can crawl through, but the killer cannot.
Hotel Murderer - An 8 player game where the murderer only has to kill 4 players to succeed. You spend 90 seconds looking for 3 separate keys to unlock separate 3 chests in order to win the game. 1 key + 1chest = 1 evidence Each night lasts 45 seconds in which the killer can kill you. You have 24 rooms and you have to enter a room before night falls or you automatically die. At the end of the night, all players get to vote who they believe is to be the killer. The killer is hidden among you and he often has to follow you to figure out in which rooms you've hid for that night. The killer can only enter 1 room per night.
Once you enter a room you may not exit it until the end of the night, unless you have a consumable flashlight for that round.
As a player you can use a flashlight to keep searching for clues during the night while the killer is out there looking for you. You may also use a padlock to lock the room you're in so the killer can't get in.
A player who collected an evidence cannot be the killer. A player who uses a flashlight can see if any other people are using a flashlight. The killer cannot pick up items and cannot collect evidence, the items teleport to a different locations when he picks them up.
