This sounds like a lot of fun! Secret Hitler is multiplayer card game that saw a wildly successful Kickstarter campaign last year. The game is set in 1932 Germany and mashes the best game mechanics of Werewolf and Mafia with a little bit of bluffing from Bullsh*t.
A Liberal majority must make sure that they keep control of the government or risk a "secret Hitler" from taking over and enforcing a Fascist government. The video above describes it much better than I can. Expect the card game to go on sale sometime in April 2016 to the general public. Hilarity to ensue.
