📋 About This Mod
A mod by JkKILER
Description
In this mod you will find 2 full length quests with at least 13 new (cell) locations to explore. Includes 3 new weapons, a new armor, and more.
This mod begins as you walk behind Megaton (by the sniper rock) and find a gruesome scene. A dead body with a note discarded in haste. Noticing how brutally destroyed the body is, you decide to at least look at the note. You discover the location of a man who quite possibly killed this person. The question is, should you become involved? This isn't your fight, and you don't even know who this person was. Why would you involve yourself in someone else's business?
Requirements
All this mod requires is Archiveinvallidation to allow for correct texture, and mesh placement.
It might also be a good Idea to have a character of at least level 15 before you begin this. Or one that is particularly strong.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Solid endorsement count (682) shows the community digs it
- Adds a decent chunk of content: 13 locations, 3 weapons, and armor
- Quest start is easy to find—just check behind Megaton
⚠️ Cons
- Last updated in 2014—might have compatibility issues with current setups

💡 Beginner Tips
- Make sure you have Fallout 3's official patches or a mod manager like FOMM to avoid load order issues.
- The quest starts behind Megaton—look for a 'messy scene' to trigger it.
- Since it's an older mod, test it early in your playthrough to catch any conflicts with other quest mods.
