To get the definitive experience, you must download three specific mods from Nexus Mods. Here is the breakdown.
If you search for "Fallout 4 2B mod," you aren't looking for a single file. Instead, you are looking for a suite of mods created by talented community artists. The core experience usually revolves around:
While no single mod turns Fallout 4 into NieR: Automata mechanically, the best combinations come frighteningly close to capturing 2B’s aesthetic spirit.
One of the biggest frustrations with Fallout 4 is the clunky third-person animation. However, 2B mods have pushed the community to fix this. To truly enjoy playing as 2B, you will want:
When these are combined with the physics-enabled skirt, walking through Diamond City actually feels like controlling 2B, not a generic settler.
Final Score: 9/10 – One of the best character crossover mods ever created for any Bethesda game.
In the vast, modding-driven ecosystem of Fallout 4, few crossover concepts capture the imagination quite like the hypothetical “2B Mod.” On the surface, the idea seems absurdly incongruous: YoRHa Unit 2B, the stoic, gothic battle-android from the post-apocalyptic philosophical masterpiece Nier: Automata, wandering the irradiated ruins of Boston. She trades her fluid, balletic combat against machine lifeforms for a rusty pipe pistol and a fight against feral ghouls. Yet, it is precisely this dissonance—the collision of elegant Japanese androgyny with gritty American atomic decay—that makes the concept so compelling. A fully realized 2B mod is not merely a costume change; it is a narrative and mechanical promise that recontextualizes the player’s relationship with the Commonwealth.
First and foremost, the aesthetic clash is the mod’s primary draw. The vanilla Fallout 4 aesthetic is one of scrappy, utilitarian desperation: duct-taped armor, patched vault suits, and the bulky, dieselpunk silhouettes of Power Armor. 2B’s design—a sleek, black mourning dress, white thigh-high heels, and a blindfold hiding eyes that have seen too much—is an alien artifact. Mods that add her character typically excel when they refuse to “wastelandify” her. The power of the mod lies in the visual friction: seeing her stand immaculate amidst the mud and rust of Diamond City, or watching her perform a perfect backflip over a Super Mutant. This isn’t immersion-breaking; rather, it creates a new form of narrative tension. She is not a survivor adapting to the wasteland; she is an unstoppable force imposing her own reality upon it.
Mechanically, a proper 2B mod demands a complete overhaul of Fallout 4’s combat loop. The base game’s gunplay is weighty and deliberate, prioritizing cover and V.A.T.S. In contrast, Nier: Automata is a character-action ballet of canceling animations, aerial combos, and seamless pod-fire support. Therefore, a successful mod would need to introduce new systems: a light/heavy melee framework for her Virtuous Contract katana, a deployable Pod (retextured as a modified Mr. Handy or Institute laser drone) for suppressive fire, and a dodge mechanic with temporary invincibility frames. Even more ambitiously, the mod could integrate the “Plug-in Chip” system into Fallout 4’s perk chart, allowing players to trade health for auto-heal or install an “OS Chip” that silences the Sole Survivor’s desperate internal monologue. This transforms the game from a survival RPG into a stylish action hybrid, offering veteran players a new challenge: conquer the Glowing Sea without ever firing a ballistic weapon.
Beyond aesthetics and mechanics, the most profound layer of the 2B mod is thematic. At first glance, the themes of Nier: Automata (existential despair, the futility of purpose, the blur between machine and soul) align surprisingly well with Fallout 4’s central questions (What is humanity? Can a synth have a soul?). However, 2B’s presence creates a fascinating contradiction. The Sole Survivor’s journey is driven by hope: finding Shaun, rebuilding the Minutemen, choosing a future for the Commonwealth. 2B’s journey, by contrast, is driven by the weight of endless, cyclical tragedy. A lore-friendly integration of her character would not make her the hero. Instead, she would act as a tragic mirror. Imagine a custom quest where the Railroad mistakes her for a Gen 3 synth, only to realize she is something far older and sadder. Picture her silent judgment as the player sides with the Institute—another “glorious” hierarchy built on disposable slaves. The mod would not end with 2B saving the Commonwealth; it would end with her standing at the edge of the crater that was the Institute, whispering to herself: “Indeed, it is a vicious cycle.”
Of course, practical challenges abound. Rigging 2B’s flowing skirt and high heels to Fallout 4’s clunky skeleton is a nightmare of clipping and broken animations. Lip-syncing for custom voice lines (pulling from Nier’s sound files) is often jarring. Most existing “2B mods” on Nexus Mods are, in reality, simple armor replacers. They give the Sole Survivor the look of 2B, but not her essence. The true, unreleased mod—the one modders dream of but few attempt—would require a team of animators, quest designers, and combat programmers. It would be less a mod and more a total conversion.
In conclusion, the Fallout 4 2B mod represents a genre of modding known as “transformative friction.” It is not about fixing Bethesda’s game or adding lore-friendly content. It is about the beautiful, violent collision of two distinct artistic visions. When you install that mod, load your save, and watch 2B punch the launch code for the Yangtze submarine, you are no longer playing Fallout 4. You are playing a new text—a dialogue between American atomic ruin and Japanese post-human melancholy. And for a few glorious hours, as the blindfolded android cuts down a deathclaw with a katana, the wasteland finally feels like a stage worthy of a tragic opera.
Finding a "proper" 2B mod for usually refers to the 2B (Nier: Automata) Character and Outfit
mods, which are among the most popular character conversions in the community. These mods typically consist of a high-quality character preset (face) and her iconic YoRHa No.2 Type B outfit. Essential 2B Mod Components

: This provides the face model to match 2B. These are found on Nexus Mods and require the plugin to work. 2B Outfit (YoRHa No.2 Type B)
: There are several versions, but the most detailed ones often include the dress, blindfold, and hair. Some versions are available on Nexus Mods
, while others (often more "adult" or high-fidelity versions) are hosted on external sites like Body Replacer (CBBE) : Almost all 2B outfits require Caliente's Beautiful Bodies Enhancer (CBBE)
to display the body shape correctly. Without it, the outfit may not fit the character model or could cause textures to glitch. Installation Requirements fallout 4 2b mod
For these mods to function properly, you must have the following base tools installed: F4SE (Fallout 4 Script Extender) : Required for LooksMenu and advanced outfit physics. BodySlide and Outfit Studio

Bringing 2B from NieR: Automata into the Commonwealth of is more than a simple skin swap; it is a full conversion that merges YoRHa’s sleek, existential aesthetic with the gritty retro-futurism of the wasteland. To achieve the definitive "2B" experience, you need a combination of character presets, outfits, and even custom AI behavior. 1. The Foundation: Visuals and Presets
To get the face and body right, you must use specific character creation tools and presets.
2B LooksMenu Preset: This is the gold standard for achieving 2B’s facial features. It utilizes a modified head mesh and custom textures to mimic her appearance from the 2017 game.
Requirements: For the best results, you'll need the LooksMenu extension and Hi-Poly Faces to ensure the facial structure is smooth and high-fidelity.
Hair & Eyes: Use Sun's Hepsy Hairs for her iconic bob and The Eyes of Beauty for her distinct gaze beneath the blindfold. 2. The Gear: Outfits and Weapons
You can't have 2B without her signature Gothic Lolita-inspired tactical gear.
YoRHa No. 2 Type B Outfit: Often found as the "COCO 2B Wedding Outfit" or general YoRHa packs, these mods include the dress, blindfold, and stockings.
Customization: Many of these outfits are built for the CBBE (Caliente's Beautiful Bodies Enhancer) body, allowing you to use BodySlide to adjust her physique to your preference.
Weapons: Look for weapon ports that include the Virtuous Contract (short sword) and Virtuous Treaty (greatsword). Some packs even include Pod 042 as a functional or cosmetic companion. 3. The Companion: YoRHa Followers
If you’d rather travel alongside 2B than play as her, several follower mods exist.
Euro 2B Follower: This mod adds a 2B companion to the game world. While she is essential in combat and arrives with a custom laser gun and sledgehammer, note that early versions may have limited interaction options like trading or dismissing.
Advanced AI: Some users have even drafted concepts for replacing the Institute Synths with YoRHa androids to fully overhaul the game’s narrative vibe into a NieR-style "android uprising". 4. Technical Essentials
To make these mods work, you must have the following framework installed: Mod Organizer 2
Integrating the iconic 2B from NieR: Automata into the wasteland of To get the definitive experience, you must download
usually involves more than just a skin swap. To make the mod feel authentic and gameplay-rich, here are some feature ideas that bridge the gap between android technology and post-apocalyptic survival. Combat & Gameplay Features
Integrated POD Tactical Support: Instead of a standard companion, include a functional POD drone that follows you. It could provide fire support, scan for loot (replacing the V.A.T.S. highlight), or act as a mobile crafting station for specialized "Android chips."
Combat Bracing & Mobility: Implement a custom animation set that replaces the standard clunky wasteland movement with 2B’s signature fluid dodges and dashes. You could even add a "Perfect Dodge" mechanic that triggers a brief slow-motion effect, similar to the gameplay in NieR: Automata.
Self-Destruct "Last Resort": A high-risk, high-reward ability that mirrors 2B’s self-destruct. It deals massive AoE damage at the cost of most of your health and creates a unique "battle-damaged" visual state for the armor until repaired. Customization & Immersion
Plug-in Chip System: Replace standard armor mods with a "Plug-in Chip" interface at Power Armor stations or specialized benches. These could provide unique bonuses like "Auto-Heal," "Shockwave" on melee hits, or "Bullet Resist" that scales with your level.
Reactive Visor HUD: A custom UI overlay that activates when 2B’s blindfold/visor is equipped. It could display enemy health bars and levels in the NieR digital aesthetic directly on the screen without entering V.A.T.S.
Weapon Fusion: Create a unique crafting path to "port" 2B’s swords (Virtuous Contract/Treaty) into the game. These shouldn't just be high-damage swords; give them a "floating" holster animation to mimic how weapons are carried in the original game. Integration with Fallout Systems
Institute Origin Story: Use an "Alternate Start" style quick start to explain 2B's presence as a rogue, hyper-advanced Institute synth experiment. This provides a lore-friendly reason for her superior technology and lack of "human" needs like food or sleep.
Cybernetic Repairs: Change the way the character heals. Instead of Stimpacks, 2B might require "Coolant" or "Circuitry Parts," making her survival depend on scavenging high-tech components rather than organic medicine.
To get the full 2B experience in Fallout 4, you’ll usually need a combination of three types of mods: a face preset, an outfit mod, and occasionally a follower mod. 1. The Face: 2B LooksMenu Preset
This is the most popular way to get 2B’s face. It uses a custom head mesh and textures to replicate her look.
Requirements: You must have LooksMenu and the Fallout 4 Script Extender (F4SE) installed for presets to work.
Key Dependencies: For the exact look, you typically need Hi-Poly Faces, The Eyes of Beauty, and specific hair mods like Sun's Hepsy Hairs.
How to Apply: In-game, open the console and type slm 14 (for the player character). Navigate to the "Presets" tab and select the 2B entry. 2. The Outfit: Yorha 2B Outfit
Finding the "canonical" outfit can be tricky because some versions are hosted outside of Nexus Mods due to licensing.
Nexus Versions: Search for "2B Outfit" or "Yorha" on Nexus Mods. Some "mashup" mods or wardrobe packs (like VTAW) include 2B-inspired pieces.
Body Type: Most 2B outfits are built for the CBBE (Caliente's Beautiful Bodies Enhancer) body. You will likely need to run BodySlide and Outfit Studio to "batch build" the outfit so it fits your character's specific body shape without clipping. 3. The Companion: Euro 2B Follower
If you don't want to play as 2B but want her by your side, there are follower mods available. While no single mod turns Fallout 4 into
Features: These typically add 2B as a standalone NPC who doesn't take up a standard companion slot.
Limitations: Be aware that some older 2B follower mods may have basic AI, meaning they might not be dismissible or able to sneak effectively. Installation Tips
Mod Manager: Use Vortex or Mod Organizer 2 instead of manual installation to avoid breaking game files.
Load Order: Use LOOT (Load Order Optimisation Tool) to ensure your presets and scripts load in the correct sequence. Mod Request - Nier:Automata follower mod! : r/FO4mods
