Capers is a game by Craig Campbell (NerdBurger Games) about superpowered gangsters and law enforcement in the Roaring Twenties:
“
Players portray exceptional people – called "capers" by the general populace – who have been gifted with superhuman powers that defy the laws of science. You can play a gangster working to make his fortune in the vice-riddled 1920s. Alternatively, you can portray a member of law enforcement working to bring these criminals to justice.”
It was played as part of the Bluff City arc "Extracurricular: Out of Time", which follows two heroes from the earlier Masks arc who have been transported to Blough City and must work with a local to solve a mystery and get home.
