Core Keeper Maps & Locations Guide: Every Area Covered

Q: What order should you fight the bosses in Core Keeper?

Glurch in the Dirt Biome first, then Ghorm in the Clay Caves, then The Hive Mother in the Forgotten Ruins. Their remains power the Core, which opens Azeos' Wilderness and the later biomes.

Q: How do you beat Ghorm?

Use ranged weapons from outside its circular path. Ghorm follows a fixed track and does not deviate, so standing off the route and firing turns a dangerous fight into a safe one.

Q: What is the ore progression in Core Keeper?

Copper, tin, iron, scarlet, octarine and then galaxite. Each tier needs tools made from the previous one, so pickaxe upgrades pace how far you can explore.

Q: Do skills matter in Core Keeper?

Yes. Mining, melee, ranged, fishing, cooking and gardening all level through use rather than by picking a class, so how you play gradually becomes what your character is good at.

Q: Where should you build your base?

Directly around the Core. Boss progression, crafting and storage all route back there, and a base built somewhere else turns every session into a commute.

Researched and editorially reviewed. Updated August 12, 2026.

Core Keeper starts you in the dark beside a dormant Core with a pickaxe and nothing else. Mining outward reveals biomes, bosses and ore tiers that climb from copper through scarlet and octarine, and the whole game is a slow negotiation between how far you have dug and how well equipped you are to survive what is down there.

Core Keeper features distinct areas with increasing difficulty. This guide covers every major location in progression order: what to do, what to get, and when to move on. For the step-by-step path, see our walkthrough.

Exploration Tips

Clear areas in order: The Core → Dirt Biome → Clay Caves → Forgotten Ruins → Azeos' Wilderness. Skipping areas means missing resources you'll need later.
Check every corner: Hidden caches and secrets are often in non-obvious locations.
Match your equipment: Some areas favor different equipment types.
Read the walkthrough: Our walkthrough provides exact progression milestones for each area.
Don't rush: Clearing an area fully gives more resources than speedrunning two areas.
