Apocalpse Keys by Evil Hat is a ttrpg Powered by the Apocalypse engine.

I must be weird, but doing good and being monstrous just make a game interesting to me.

I am not advertising for it, but I know there are like minded people here, specifically Nem who introduced me to my very first ever Powered by the Apocalpyse game. Ty!

Apocalypse Keys <the code for a URL seems to be flummoxed. Someone more technical can tell me how to fix it.>

I do like Powered by the Apocalypse.

Thanks Pandemonium. Apocalypse Keys looks like an interesting twist on a PbtA game. By coincidence or design, it looks like its uses Lady Blackbird's keys concept as the cornerstone of its characters. That's a good idea imo, keys work well in Lady Blackbird.
