From publisher blurb:
AWESOME... and ADORABLE
The Cat Hack takes the OSR rules of The Black Hack and modifies it to work with minimalist setting where the player characters are all cats!
Humans are frail creatures. Most of them aren't equipped to deal with the supernatural. That's where cats come in!
Only cats can see the threats. Only cats have the spells and abilities to deal with them. Once they're done with their nap, of course!
The game features four kitty classes: Battle Cat, Lithe One, Shaman Cat, and Pretty Kitty. While the Shaman Cat specializes in them, all cats have access to spells!
The game is set in the modern day by default, with a sort of urban fantasy vibe. However, there are notes for using kitties in a traditional fantasy setting or a scifi setting with The Black Hack and The Space Hack, respectively!
This is a complete game! The Black Hack is not required, tho I encourage everyone to purchase the excellent parent game.
Everything you need to start your adorable adventure is here, in a streamlined 16-page OSR ruleset!
