Fantasy Kingdoms of Rats, Living and Warring beneath Manhattan. A complete rules-lite tabletop RPG for game master or solo play.


Kings and nobles vie for power in a swirling labyrinth of political intrigue. Warriors and wizards battle for treasure, knowledge, and adventure. Scavenge through items discarded by fearsome "giants" to fashion clothes, weapons, armor, and homes. You or your players take on roles of rats, mice, and other creatures living in the sewers of Manhattan Island.


The book contains:



  • Capsule histories for each kingdom
  • Details for rats and cultures
  • Maps of the "Understreet"
  • Numerous scavenge tables
  • Adventure ideas and story hooks
  • Important NPCs
  • And more!


This is a rule-lite update of the previous 5e version of the game that can be played solo or with a GM. I plan on creating a new edition for 5e using the new Creative Commons content WotC has released in the future.
