So the theme for AC last year was "secret societies." As soon as my BF mentioned the KGB, I knew exactly what kind of badge would be appropriate for him, and made one for myself in the process.
Done in the style of "Papers, Please", an independently-made document-checking game taking place in turbulent eastern Europe during the Cold War. Play it or risk osprey bites because it's friggin' awesome.
Glory to Arstotzka.
