🎯 Tips & Tricks
Make sure the mod is placed in the correct folder (usually Subnautica/BepInEx/plugins) if using BepInEx.
Check the mod's page for any required dependencies like QModManager or BepInEx — the description doesn't mention them, so test after install.
If the tank doesn't appear in your inventory, try crafting it at a fabricator — it might be a blueprint you need to unlock.
