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.[/*]
