What is it about?
Something is wrong behind the walls of everyday life. Rats in the Walls follows vulnerable people into cosmic horror: disturbing clues, dangerous discoveries and encounters that leave a mark. This profile uses the original open rules from 2018.

At the table
Two six-sided dice, professions and sanity support direct, tense investigations with little preparation between the story and the next decision.
