These maps (3) work with the standalone adventure "Troubles in Otari" (TiO) purchased from Paizo for Level 2 PCs. While many of the maps do not require that Adventure, it is highly recommended to purchase it as it offers a nice pivot from the Beginner Box (BB) Campaign where the heroes end up at Level 2. It is also recommended, GM's purchase the PF2E Bestiary (this Adventure supports them).
The Beach Camp Encounter Only map will require the Adventure Path, but the Beaten Forest Path and the Upgradeable Map can work with any adventure story. After completing Chapter 1 of TiO, the heroes will be Level 3 and Tamily gives them the Beach Camp as a "Base of Operations."
This Adventure allows the PCs to "upgrade" the Beach Camp into thheir "Base of Operations!" It includes references to some of Paizo's subsystems and tools to track and provide perks to the heroes as they clean, repair, decorate, and enhance the Beach Camp to a true "Base of Operations!"
Naturally, as the GM, you can use this upgradable map for any adventure where you want to provide the players with alternative progression or rewards.
