Core Keeper's major content update **1.3 "Riders of the Underground"** is live as of **21 September 2026**. This marks the first chapter of Pugstorm's _Road to the Maw_ trilogy, fundamentally changing how players navigate the underground world.

## Riding and traversing the depths

Exploring an ever-expanding underground map on foot often turned into a chore once the early biomes were conquered. Update 1.3 addresses this friction with two key mobility mechanics:

- **Rideable Mounts:** By crafting saddles, players can now mount underground cattle. A custom interface lets your group name mounts and manage their behaviour during expeditions.
- **The Hookshot:** An off-hand item allowing players to zip across chasms, pits, and underground rivers without having to lay down wood bridges every few steps.

The update also brings a brand-new moss sub-biome nestled inside the Forgotten Ruins, three new pets (including _Hoppet_ and _Azeos Jr._), and fresh gear tailored to expand magic and summoner playstyles.

## How your dedicated server gets updated

On Steam, the server binary (_Core Keeper Dedicated Server_, App ID `1963720`) was pushed concurrently with the main game client to prevent version mismatch errors.

On TickServ, there is zero manual maintenance required:

- **Automatic updates on boot:** Our Core Keeper servers run a lean image that pulls the latest SteamCMD release on every startup.
- **Immediate availability:** If your server is stopped, its next launch will run 1.3 straight away. If it is currently running, a simple restart from your TickServ dashboard will pull the update.

## What about existing save files?

Existing worlds and character progress are fully compatible with 1.3.

Keep in mind that, as with any procedural update, the new moss sub-biome and its unique resources will only generate in chunks that **have not been explored yet**. If your group has already uncovered a large perimeter around the Core, you will simply need to tunnel outward into uncharted territory.

## What this doesn't solve

Older worlds that have been explored over dozens of hours still demand more RAM than fresh maps: for groups with more than 4 active players on a mature world, we recommend staying on the 8 GB tier. Additionally, if you use unofficial community mods, some may require a few days for their creators to adapt them to 1.3.
