Data Sources
How we extract and validate Fallout 4 game data
All weapon stats, perk effects, armor values, and game mechanics are extracted directly from Fallout 4 game files (*.esm, *.esp) using FO4Edit, the community-standard modding tool for data extraction and analysis.
Data Extracted:
- Weapon base damage, fire rate, accuracy, range, AP cost
- Weapon modifications and their stat multipliers
- Perk effects, requirements, and rank progression
- Armor damage resistance, energy resistance, radiation resistance
- Legendary effect formulas and scaling mechanics
- Settlement resource requirements and happiness calculations
Used for cross-referencing game mechanics and validating formula accuracy
Community testing data for complex mechanics (e.g., Two Shot accuracy)
Official documentation for the data extraction tool
DPS (Damage Per Second)
DPS = (baseDamage × damageMultiplier + explosiveDamage) × fireRate × hitChanceEHP (Effective Hit Points)
EHP = baseHP / (1 - (DR / (DR + incomingDamage × 10)))AP Cost
AP = baseAP × (1 + Σ modAPMultiplier)All formulas are documented with source citations in the codebase and can be reviewed on our GitHub repository.
Sample of the 324 optimized game assets extracted from Fallout 4 files:
Weapons (171 total)
Perks (108 total)
Armor (45 total)
All assets optimized to 91.3% compression (14.83 MB → 1.29 MB) using Sharp with quality=85, maintaining visual fidelity.
Note: While we strive for 100% accuracy, some game mechanics (particularly complex perk interactions) may have approximations. If you notice any discrepancies, please report them using the "Report Data Error" link in the footer.
