📋 About This Mod
Redoes the entire sea floor found in Fallout 3, No more flat shallow sea floor now behold dark and deep sea floors layed with details and things to discover.
The mod completely reworks the flat sea floor, left over by bethesda because they cant work time onto the sea floor i did it for then and originally they only used 4 different types of rocks, hardly any rocks, rocks not even rotated, and nothing to find... Or even things to explore and find.
This sea overhaul is also compatible with Fallout 3 Rebirth. And is fully navmeshed up.
Untill Now..
-Fixes a rock near the car parking lot at the broken half of rivet city
-Removes the flat Bethesda's sea floor and creates a more immersive and sea like floor
-Fixes badly placed rocks by Bethesda
-Pockets of even lowered sea floor
-adds rocks and more unique rocks and formations
-Sea floor is extremely deeper then before mixed with different types of rocks and detailing with many things to find and do it should make a change then avoiding the water.
What can you find at the depths of the sea?
-That would be too easy now wouldnt it.

- Turns a boring, flat sea floor into a detailed, explorable environment—huge for immersion.
- Works with Fallout 3 Rebirth, so you can stack it with other overhauls without breaking your game.
⚠️ Cons
- Last updated in December 2020, so it might not be fully compatible with the latest Fallout 3 patches or mods.

- Compatibility is only confirmed with Rebirth; other mods that touch the same areas might conflict.
For Fallout 3 explorers who want to turn the ocean into a creepy, rewarding place to scavenge. If you're running Rebirth or just want a fresh take on the Capital Wasteland's waters, this is for you. Skip it if you don't care about underwater environments or prefer gameplay changes over visual overhauls.
💡 Beginner Tips
- If you're using Fallout 3 Rebirth, load this mod after it to ensure the sea floor changes take priority.
- Use a mod manager like FOMM or Vortex to avoid overwriting files manually.
- Test the sea floor near the Anchorage Memorial or the Tidal Basin to see the changes quickly.
