About Core Keeper
Core Keeper is a sandbox survival game developed by Pugstorm and published by Fireshine Games. It entered Steam Early Access on March 8, 2022, and reached full release on August 27, 2024, for PC via Steam, PlayStation 4, PlayStation 5, Xbox One, Xbox Series X/S, and Nintendo Switch. Core Keeper holds a Metacritic score of 86 and a Very Positive rating on Steam.
The game is set entirely underground. Players find themselves drawn to a vast cavern by the light of an ancient artifact called the Core, which they inadvertently awaken upon arrival. From there, the goal is to explore the procedurally generated network of tunnels and biomes surrounding it, gather resources, build a base, and uncover what the Core actually is.
Mining is the backbone of progression. Players break through different terrain types to collect materials used for crafting tools, weapons, armor, and base components. Each biome introduces new enemy types, unique resources, and a boss that must be defeated to push further into deeper and more demanding areas. Farming and automation systems allow players to build more self-sustaining operations as their base grows over time.
The game supports solo play and online co-op for up to eight players, with the world shared across all participants in a session. Playing with others scales the challenge and opens up more complex building and farming setups.
Post-launch updates have expanded the game significantly, adding new biomes, bosses, crafting systems, and mechanics since the 1.0 launch. Steam Workshop mod support was added in early 2026. Critics have frequently compared Core Keeper to Minecraft, Terraria, and Stardew Valley for its blend of exploration, building, and survival systems in a distinct underground setting.

Core Keeper draws comparisons to Minecraft and Terraria for its mining, crafting, and building mechanics, and to Stardew Valley for its farming and slower-paced base development elements. It combines all three influences in a top-down pixel art style set entirely underground, giving it a distinct atmosphere and progression flow of its own.
