Developer Pugstorm and publisher Fireshine Games have officially unleashed Riders of the Underground — the massive, free 1.3 update for underground sandbox survival hit Core Keeper — available right now across all platforms.
Ride Into the Depths
The headline feature speaks straight to every explorer’s heart: you can now tame and mount cattle as your very own steed. Craft a Saddle or Racing Saddle, pop it onto your favourite beast, and gallop across the caverns in style. Name your mount, set its behaviour — stay, roam, or follow close behind — and forge a bond with your loyal companion as you dive deeper than ever before.
Hookshot — Reach New Depths
Stuck facing a gaping chasm? The brand-new Hookshot lets you latch onto solid surfaces and pull yourself across pits, water, and impassable drops. No more building endless bridges — just aim, fire, and soar. It’s a game-changer for exploration and opens up hidden corners of the world that were previously out of reach.
Explore the Moss Sub-Biome
Deep within the Forgotten Ruins, a lush, mysterious new region has emerged: the Moss sub-biome. Shaded, humid, and brimming with verdant life, it’s home to the sleek, raptor-like Orex cattle — and plenty of secrets waiting to be uncovered. Venture in, gather rare resources, and meet the creatures that make this hidden grove their home.
Befriend New Companions
What’s an adventure without friends? The update introduces a host of new pets to befriend, each with their own unique personalities and abilities. Whether you’re looking for a loyal follower or a helpful ally in combat, there’s a new tiny companion waiting to join your underground journey.
