Nicely done hack for running a PbtA game of werewolves fighting evil spirits and demons in a world similar to our own but with supernatural underpinnings.
The setting is Mexico and the setup is very cool. The mechanics (while laser-focused on getting the type of story the game want's to tell going) are not nailed to the locale and could be shifted elsewhere if you really want to tell a similar story set in another place. It has a local focus, the pack in Los Cazados should be invested in the specific territory they're trying to take care of.
This is a minigame of Urban Shadows so it doesn't add detailed crunch, though, and if you're looking to translate a certain other shapeshifter game with high fidelity to mechanics it's not going to do what you want.
But if you enjoy these themes, this is a very good take on werewolves for Urban Shadows.
