✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved with 766 endorsements and over 64k downloads.
- Progressive upgrades give a clear sense of progression.
- MK4 speed matches the Seamoth, making it a viable late-game travel option.
⚠️ Cons
- Requires BepInEx, which adds an extra setup step for players unfamiliar with mod loaders.
- Only affects speed—no other gameplay changes, so it's a one-trick pony.
For Subnautica players who want to zip around faster without building a Seamoth every time. Great for explorers who love the Seaglide but find it too slow late-game. Skip if you're looking for deeper gameplay overhauls—this is purely a speed boost.
💡 Beginner Tips
- Make sure BepInEx is installed correctly before adding this mod—check that the BepInEx folder is in your Subnautica root directory.
- After installing, launch the game once to generate the necessary folders, then place the mod DLL in the BepInEx/plugins folder.
- If you're using a mod manager like Vortex, it can handle BepInEx installation for you, but manual setup is straightforward if you follow a BepInEx guide.
