Hydra 3.6.0 Lumen – Decky Plugin Debut + Smarter Backup Controls

👋 Hey there!

We’re back with Hydra 3.6.0 — codename Lumen. This update brings something many of you have been waiting for: full integration with Decky Loader via our brand-new plugin, plus some powerful improvements to how you manage backups and favorites inside Hydra Launcher.

Let’s dive in.


🧩 Introducing the Hydra Decky Plugin

Hydra now plays natively with Game Mode on the Steam Deck thanks to our official Decky plugin!

If you’ve enabled developer mode in Decky Loader, you can install it right now using this link:
👉 hydra.la/decky
It’ll also be available on the Decky Store very soon.

Here’s what the plugin can do:

  • Track playtime across both Steam-native and non-Steam games — right from Game Mode

  • Manage Cloud Saves seamlessly:

    • Automatically backs up your game when it closes

    • Allows restoring backups directly from the plugin

  • Receive Steam notifications inside Game Mode:

    • Get alerts when a friend starts playing or sends you a friend request

💡 Note: To use the plugin, make sure Hydra Launcher is updated to version 3.6.0 or later and that you're logged in via Desktop Mode.

An active Hydra Cloud subscription is required for Cloud Save features to work.
However, playtime tracking and Steam notifications work without a subscription.


📌 New in Cloud Save Management

We’ve added more control over your backups:

  • Pin your backups:
    Mark a backup as frozen so it won’t be overwritten by future automatic saves.

  • Rename backups:
    Whether they’re manual or automatic, you can now give backups a custom name.

  • Favorites, now synced:
    Favoriting a game is now tied to your Hydra account, not just your local device — perfect for syncing across machines.


We’re really excited about this release — especially what it means for Steam Deck users. With the plugin and new backup tools, managing your library and saves just got a whole lot easier.

Until next time — enjoy the ride, and keep playing. 🎮
