Apocalypse Keys is a mystery tabletop role-playing game about monsters who decide to save the world, designed by Rae Nedjadi and published by Evil Hat Productions.

The game is inspired by Hellboy, Bureau for Paranormal Research and Defense, Men in Black, Penny Dreadful, and Doom Patrol.

[1][2] Players create monster characters based on emotional wounds instead of typical archetypes, and their world-saving organization operates like a queer chosen family.

[1][2] Nedjadi designed the game with emotional safety in mind, driven by the questions, “How do I build in a sense of narrative power that's not just in the GM’s hands?

[6] Evil Hat Productions acquired publishing rights in March 2021[7] and ran a Kickstarter campaign for Apocalypse Keys in October 2023, raising $165,883 from 3,226 backers.
