The Smoldering City is your central hub, where you unlock upgrades, new buildings, and global bonuses that persist across all your expeditions. Earning Citadel Resources from successful settlements allows you to invest in these upgrades, making future runs easier and more diverse. Prioritize upgrades that boost resource production or villager Resolve early on.
The World Map presents a branching path of expeditions. Each node represents a new settlement location with unique biome modifiers and rewards. Plan your route carefully, considering the biome's challenges and the rewards offered. Aim to clear paths to unlock new biomes and gain access to more powerful upgrades for the Smoldering City.
