The Undergrounds

The Undergrounds is a biome in Core Keeper and serves as one of the game’s subterranean regions. It is notable for being the only biome that does not display its name in the top-right corner of the fullscreen map.

Fishing from normal water in the Undergrounds yields biome-specific catches, and the biome also contains unique terrain-based resources and ore boulders. In general play, it functions as a standard underground exploration area rather than a special event location or boss-only zone.

• The Undergrounds is the only biome whose name is omitted from the fullscreen map’s top-right display.
• It supports normal-water fishing with a dedicated catch pool.
• It includes unique items obtainable from terrain and from terrain in specific scenes, as well as ore boulders.
