⚠️ Common Mistakes
- Installing multiple mods that modify the same files without checking compatibility
👍 Pros
- Over 11,000 downloads show real interest from the community.

- Fresh content for Subnautica veterans who've seen everything else.
👎 Cons
- No detailed description of what the unique behavior actually is—you'll have to discover it in-game.
