Core Keeper

Core Keeper is a survival game and sandbox game developed by Pugstorm and published by Fireshine Games. Set in a procedurally generated underground world, the game combines mining, crafting, farming, automation, and combat while supporting single-player and cooperative multiplayer for up to eight players. Critics have compared its mechanics and tone to Minecraft, Terraria, and Stardew Valley for blending exploration, base-building and survival systems within a darker, atmospheric cave setting. The game entered Steam early access on 8 March 2022, where it received positive reviews for its progression systems, art style, tone, and accessibility to new players and co-op groups. During this period it surpassed one million sales and received multiple award nominations. Core Keeper left early access with its 1.0 release on Windows and Linux on 27 August 2024, followed by versions for PlayStation 5, Xbox Series X/S, Nintendo Switch, PlayStation 4 and Xbox One on 17 September 2024. The game received a port to Nintendo Switch 2 on 26 January 2026, with owners of the original Switch version receiving it free of charge. The full release was met with generally favorable reviews, including an 85/100 score on Metacritic. The game has continued to receive free post-release updates with new content and features.
