⚠️ Common Mistakes

Installing multiple mods that modify the same files without checking compatibility

👍 Pros

Huge community trust (27,577 endorsements) — this is the backbone of Subnautica modding
Saves you hours of fiddling with game internals; just plug and play
Actively maintained as of early 2023, so it's still relevant for current mods

👎 Cons

Last updated in February 2023 — might not support the latest game patches, so check compatibility
It's a library, not a content mod — you won't see new items unless you use it to make your own
Requires some modding knowledge to get the most out of it; not for casual players
