Pugstorm and publisher Fireshine Games released the free Core Keeper update Riders of the Underground on September 21, 2026 (Japan time), for PC, PS5, PS4, Xbox Series X|S, Xbox One, Nintendo Switch 2 and Nintendo Switch. The update is version 1.3. Its centerpiece is the Saddle, a new item that turns any livestock animal in the game into a mount. Players can ride those animals, rename them, and set their behavior to stay put, wander, or follow. A new sub-biome, Moss, spreads green growth through stone ruins and is home to Oreks, a reptilian livestock species. The Hookshot lets players cross rifts and gaps. Three pets arrive with different abilities: Pyokohop, described as coming from the sea, grants a slipperiness effect and attacks at range, while Azeos Jr., described as coming from the sky, can stun enemies. New weapons and armor are included, along with adjustments to mage and summoner playstyles.
The update runs as version 1.3 for Core Keeper, the mining sandbox adventure where one to eight players fight, mine, build, and craft through an underground world. Rideable animals can be renamed and given standing orders, so a player can leave one parked while exploring or keep it trailing behind as a companion. Moss sits in dark, damp corners of stone ruins, and Oreks live there. Pugstorm CEO and director Fredrik Prantare spoke about the update in an interview tied to Tokyo Game Show 2026, including a wish to eventually let players ride bosses. Two more updates are already announced: version 1.4, Trials of the Abyss, and version 1.5, Beyond the Rift. Core Keeper is sold on Steam, the Epic Games Store, GOG.com, PS5, PS4, Xbox Series X|S, Xbox One, Nintendo Switch 2, and Nintendo Switch. A trailer for Riders of the Underground is available, and patch notes are posted on the Steam news page.
