This article is based on information as of May 25, 2026. As Fallout 4 is a single-player game, there are no regular season systems like online games. However, a significant recent update, the 'Next-Gen Update,' was released on April 25, 2024. This update primarily focuses on performance improvements (such as 60FPS support) for PS5/Xbox Series X|S, stability enhancements, and bug fixes, and does not include balance adjustments that directly change the performance of Perks or weapons related to stealth builds. Please use this information as current.

Hiding in the shadows of The Commonwealth, ending everything before enemies even notice your presence… this assassin-like playstyle is achieved with the "Stealth Gunslinger" build. Precision shots utilizing V.A.T.S. and silent single strikes from suppressed pistols are truly breathtaking. This guide thoroughly explains how to construct this build, which proves incredibly effective even in high-difficulty Survival mode, covering everything from S.P.E.C.I.A.L. allocation to progression routes and recommended equipment.

What is the Stealth Gunslinger Build?

The Stealth Gunslinger build, as its name suggests, combines "stealth actions" (Stealth) with "pistols" (Gunslinger). The main objective is to maximize the attack damage bonus from a stealth state and eliminate enemies in one shot without being detected. The keys to this build are the Agility and Luck S.P.E.C.I.A.L. stats.

Agility concentrates Perks fundamental to the build, such as 'Sneak,' which enhances stealth abilities; 'Gunslinger,' which boosts pistol damage; and 'Ninja,' which dramatically increases the multiplier for stealth attacks. On the other hand, Luck is extremely important for strengthening critical hits in the V.A.T.S. combat system. By increasing critical damage with 'Better Criticals' and enabling powerful critical hits to be triggered at will with 'Critical Banker,' even formidable boss-tier creatures can be eliminated in an instant.

The true value of this build is realized by combining the 'Mister Sandman' Perk with suppressed weapons. The synergistic effect of these allows for damage multipliers typically unimaginable, turning you into an assassin who delivers nothing short of "silent death" to enemies.

S.P.E.C.I.A.L. and Perk Configuration

The foundation of the build, S.P.E.C.I.A.L. allocation, and the priority of acquiring Perks as you level up, are key to success. Here, we introduce a recommended configuration that also considers experience efficiency.

Example of Initial S.P.E.C.I.A.L. Allocation

This allocation aims to acquire key Perks early while anticipating enhancements from Bobbleheads. Specifically, by keeping Intelligence at 1 and acquiring 'Idiot Savant,' the goal is to gain explosive experience even with low INT.

S.P.E.C.I.A.L.	Initial Value	Main Purpose and Perks
Strength	1	Generally unnecessary. Raise to 3 with Bobbleheads and a SPECIAL book to acquire 'Armorer' and enhance armor.
Perception	3	In the early game, consider acquiring 'Locksmith' for exploration. Obtaining a Bobblehead will raise it to 4, also meeting the prerequisite for 'Rifleman'.
Endurance	1	Fragile build. In high difficulties or Survival mode, it's recommended to allocate 3-5 points to enhance stability.
Charisma	3	The goal is to acquire 'Lone Wanderer,' a very powerful Perk when not accompanied by a companion.
Intelligence	1	Maximize the experience bonus from 'Idiot Savant'. If 'Gun Nut' for weapon modifications is needed, raise to 3.
Agility	9	The most crucial SPECIAL stat, concentrating essential Perks like 'Sneak', 'Gunslinger', and 'Ninja'. Aim for 10 with a Bobblehead.
Luck	9	Set high for Perks that enhance V.A.T.S. criticals, such as 'Better Criticals' and 'Critical Banker'.

Perk Acquisition Priority During Level Up

It is important to proceed strategically when deciding which Perks to acquire with each level up.

Level Range	High Priority	Medium Priority	Low Priority
Lv. 1-10	Sneak (2), Gunslinger (2), Idiot Savant (1)	Locksmith (1), Lone Wanderer (1)	Armorer (1)
Lv. 11-20	Ninja (1), Mister Sandman (1), Better Criticals (1)	Sneak (3), Gunslinger (3), Critical Banker (1)	Gun Nut (1-2), Armorer (2)
Lv. 21-35	Ninja (2), Critical Banker (2), Better Criticals (2)	Mister Sandman (2), Four Leaf Clover (1), Sneak (4)	Grim Reaper's Sprint (1), Lone Wanderer (2)
Lv. 36-50	Ninja (3), Gunslinger (5), Better Criticals (3)	Four Leaf Clover (4), Grim Reaper's Sprint (3), Critical Banker (3)	Sneak (5), Mister Sandman (3)

Recommended Equipment and Companions

Appropriate equipment selection is essential to maximize the build's effectiveness.

Primary Weapons

Deliverer: A unique 10mm pistol that can be called the ultimate weapon for this build. It can be obtained by completing The Railroad quest "Tradecraft". Its high V.A.T.S. accuracy and very low AP consumption make it a perfect match for this V.A.T.S.-heavy build. The fact that it comes with a suppressor from the start is also a major advantage.
Suppressed 10mm Pistol: Extremely effective as a placeholder until you acquire the Deliverer. It's available early in the game, and a suppressor can be easily attached with the 'Gun Nut' Perk.
Kellogg's Pistol: A unique .44 pistol obtained during the main quest. It has the effect of fully restoring AP on a critical hit, making it exceptionally compatible with V.A.T.S. While powerful, it cannot be suppressed, so it's best used as a trump card after stealth has been compromised.

Primary Armor

Shadow Modded Armor: Applying the 'Shadow' modification to leather or combat armor significantly improves stealth in dark areas. This directly impacts the success rate of stealth actions, so prioritize this modification.
Chameleon Legendary Effect: Renders you invisible while standing still and crouching. This dramatically reduces the chance of being detected by enemies. Having this effect on just one piece of armor greatly enhances safety.
Increased AP Regeneration Speed: To increase V.A.T.S. usage frequency, it is recommended to prioritize regeneration speed over maximum AP.

Recommended Companions

No Companion (Lone Wanderer): The Charisma Perk 'Lone Wanderer' provides powerful effects such as reduced damage taken and increased carrying capacity when traveling alone. Companions can sometimes be a cause of detection by enemies, so if you aim for maximum stealth, traveling solo is the optimal solution.
Deacon: A companion affiliated with The Railroad. He himself excels at stealth, and his companion bonus increases Stealth Boy duration and stealth attack damage, making for good synergy.

Playstyle and Progression Guide

Here's an explanation of the playstyle suited to each stage of the build's progression.

Early Game (Lv.1-15): Primarily use the 10mm pistol obtainable around Sanctuary. First, raise 'Sneak' in the Agility tree to Rank 2 to reduce the chance of detection by enemies. Next, secure basic firepower with 'Gunslinger'. Head towards Diamond City and establish a foothold for joining The Railroad. During exploration, if detected, prioritize escape and avoid unnecessary combat.
Mid Game (Lv.16-35): Progress through The Railroad quests and prioritize acquiring the "Deliverer". The moment you obtain this weapon, your combat capabilities will dramatically improve. Acquire 'Ninja' and 'Mister Sandman' Perks to explosively increase stealth attack damage. Simultaneously, allocate points to 'Better Criticals' and 'Critical Banker' in the Luck tree to enhance V.A.T.S. decisive power. Apply 'Shadow' modifications to your armor with 'Armorer' to further solidify your stealth.
Late Game (Lv.36+): Maximize the ranks of key offensive Perks to complete the build. Acquiring 'Four Leaf Clover' (V.A.T.S. hits fill the critical meter) and 'Grim Reaper's Sprint' (defeating an enemy with V.A.T.S. restores all AP) from the Luck tree will allow you to use V.A.T.S. almost infinitely, showcasing unparalleled strength even in group combat. At this stage, formidable creatures like Behemoths and Deathclaws can be dispatched in a few shots without ever being noticed.

Using in Survival Mode

The Stealth Gunslinger build is one of the most powerful builds for Survival mode. In this mode, where damage taken from enemies can be fatal, the ability to avoid combat altogether through stealth is a major advantage. The playstyle of conquering one enemy outpost after another without being detected is highly compatible with Survival mode.

However, with an initial Endurance of 1, a weakness is that you are very fragile if you are detected or contract an illness. For Survival mode, it is recommended to set initial Endurance to 3 or higher to secure Health Points. Additionally, acquiring the 'Armorer' Perk early to supplement defense will increase stability. Furthermore, considering Perks like 'Lead Belly' to reduce the risk from contaminated water and food, or 'Chemist' to craft antibiotics, will significantly improve your survival rate in the harsh Commonwealth.

Conclusion

The Stealth Gunslinger build in Fallout 4, while requiring planned progression and appropriate equipment selection, boasts overwhelming destructive power once completed, unmatched by others. The satisfaction of ending everything with a single blow from behind enemies is a unique thrill of this build. Especially for players looking to conquer the intense Survival mode, this build will be an indispensable companion. Based on this guide, why not aim to become The Commonwealth's most powerful silent assassin?
