Cave Secrets
Cave regions beneath and beyond the starter valley hide rare crafting materials, secret rooms, and optional story beats. Caves often gate behind land unlocks and rank stars introduced in mid-game major updates. Exploration rewards couriers with new export recipes and EGO quest completions — but unprepared mayors face dead ends without lighting or tool upgrades from higher EGO tiers.
Accessing caves
Unlock adjacent land parcels until cave entrance markers appear on map or phone quests. Some entrances require specific rank stars or story quest completion.
Bring stockpiled food and tools if the game tracks spelunking stamina — check phone quest hints before long trips.
Hidden rooms and loot
Breakable walls or secondary tunnels may hide chests with blueprints, cosmetics, or rare ores. Ping co-op partners when split-screen obscures side passages.
Rare ores feed mid-tier exports — link cave zones to surface depots with couriers once safe paths exist.
Resource zones in caves
After unlocking cave harvesting EGO packs, paint resource zones over ore nodes. Workers path shorter if main elevator or shortcut unlocked.
Do not zone across blocked tunnels — clear exploration first.
Secret hunting tips
Follow audio cues and lighting differences. Return after Tier 6 traversal tools if an area seemed inaccessible early.
Community maps post-launch may mark fixed secret coordinates — verify after patches.
