Tidekeeper

What is Tidekeeper?

Tidekeeper is a mod manager built specifically for Subnautica 2. It runs natively on Windows and handles everything from browsing the Nexus library to installing, enabling, and updating your mods — without ever needing to touch a file manually.

Features

• []Browse mods in-app — The Discover tab pulls the latest Subnautica 2 mods directly from Nexus. Find, read, and install without switching windows.[/]

  []One-click installs via NXM — Click "Mod Manager Download" on any Nexus mod page and Tidekeeper handles the download and install automatically.[/]

  []Sign in with your Nexus account — Full OAuth login. Your premium download speed, endorsements, and tracking all work natively inside the app.[/]

  []Enable and disable mods — Toggle mods on or off without uninstalling them. Changes take effect on next game launch.[/]

  []Update checks — See at a glance which installed mods have newer versions available on Nexus.[/]

  []Multiple game installs — Use the environment switcher to manage separate mod sets for different Subnautica 2 installations side by side.[/]

  []UE4SS and PAK support — Works with both UE4SS script mods and PAK mods out of the box.[/]

Requirements

• []Subnautica 2 (Steam)[/]

  []UE4SS for Subnautica 2 — Use the version hosted here on Nexus Mods, not the GitHub release. The standard GitHub build will prevent the game from launching. The Nexus version is built specifically for SN2.[/]

Installation

• []Download the latest Tidekeeper x64 Setup installer from the Files tab.

  When you run the installer, you will need to click more info to be able to install Tidekeeper[/]

  []Run the installer and follow the prompts.[/]

  []Launch Tidekeeper from the Start menu or desktop shortcut.[/]

  []On first launch, click Add Environment and point Tidekeeper at your Subnautica 2 install folder.[/]

  []Optionally sign in with your Nexus account to enable NXM downloads and the Discover tab.[/]

Notes

• []UE4SS script mods are installed to Binaries\Win64\ue4ss\Mods inside your game folder.[/]

  []PAK mods are installed to Content\Paks\~mods.[/]

  []Your save files live in a completely separate location (AppData\Local\Subnautica2\Saved\SaveGames) and are never touched by Tidekeeper.[/]

  []An antivirus warning may appear on first launch — this is a known false positive that affects unsigned applications. Tidekeeper does not connect to any services other than Nexus Mods and GitHub Releases.[/]
