- Unique concept—exploring a rusting nuclear submarine in the Potomac is a fresh twist.
- Lightweight addition that fits into the game world without overhauling existing content.
⚠️ Cons

For Fallout 3 explorers who love uncovering hidden locations and want a new underwater adventure. If you're into lore-friendly additions that don't mess with the core game, this is a neat pick.

💡 Beginner Tips
- Make sure to have a high Radiation Resistance or plenty of RadAway before diving in—the Potomac is irradiated.

- Check your load order to ensure no other mods overwrite the Potomac area.
