Core Keeper – Riders of the Underground Trailer:
This free update introduces rideable mounts to Core Keeper for the very first time, bringing a brand-new way to explore the game’s mysterious world. All of your friendly cattle can now be ridden as mounts, named and given behavioral options, including commands to stay in place, roam freely or accompany the player as an adorable pal.
Make sure to take advantage of the brand-new Hookshot to leap across chasms and pits, a useful grappling hook that lets adventurers explore further afield without the need to lay down paths or bridges. Meanwhile, in the dark, hidden corners of the Forgotten Ruins, a new sub-biome emerges: the Moss sub-biome, featuring a collection of lush greenery among its stoney ruins.
Alongside these core new features, the Riders of the Underground update introduces multiple new pets, each with their own unique abilities, new weapons, accessories and armor pieces, alongside a variety of quality of life improvements.
