📊 Pros & Cons
✅ Pros
- Solid community support with 650 endorsements.
- Over 41,000 downloads shows real player interest.
- Fits the wacky prototype theme for collectors.
⚠️ Cons
- Burst fire may not suit players who prefer traditional shotguns.

- No mention of compatibility with other weapon mods.
For Fallout 4 players who love collecting unique, lore-friendly weapons with a quirky backstory. If you're a shotgun enthusiast looking for something different from the standard pump-action, this is a fun addition. Skip if you want a realistic or tactical shotgun – this is pure prototype weirdness.
💡 Beginner Tips
- Check if the mod requires any DLC or base game updates before installing.
- Test the burst fire in VATS – it might behave differently than manual aiming.
- Look for the weapon in the Commonwealth – it may be placed in a specific location or craftable.
