🎯 Tips & Tricks
Since the mod is old, check if it's compatible with your game version before installing — you might need to use the BG3 Mod Manager and load order tools.
Look for a 'Public' or 'Mods' folder in your BG3 installation to place the mod files if you're installing manually.
If you encounter crashes, try disabling other mods that affect the same areas to isolate conflicts.

⚠️ Common Mistakes
- Installing multiple mods that modify the same files without checking compatibility
👍 Pros
- Community favorite with 1,353 endorsements and 33k+ downloads — clearly a hit.
- Gives the sewers a unique Underdark vibe that fits Baldur's Gate 3's dark fantasy tone.
- More rooms and shadow creatures mean more content to explore and fight.
👎 Cons
- Last updated in December 2018 — likely outdated and may not work with current game patches.
- No installation instructions provided, so you'll need to figure out mod manager or manual setup on your own.
- Visual overhaul only — no new quests or story content, so if you want gameplay changes this isn't it.
