What is Core Keeper?

An open-world pixel-art mining sandbox set in an underground cavern. Alone or in online co-op, you gather resources, craft equipment, build and automate a base, explore biomes, and fight monsters and Titans while uncovering the Core's power.

For you if...

  • +you like setting your own pace in open worlds
  • +you enjoy alternating combat with quieter sandbox activities
  • +you want solo play and drop-in online co-op

Not for you if...

  • −you prefer guided campaigns over open-ended sandbox play
  • −you want combat without resource gathering or crafting
  • −you want farming without dangerous cave exploration

What players say

Players praise the early exploration and progression, creative base building, pixel art, and co-op. Common complaints focus on repetitive late-game biomes and bosses, grindy progression, limited weapon variety, and weak or awkward summoner builds.
