Let's be real for a second. PC Building Simulator 2 is a massive upgrade over the original, but it still feels weirdly empty sometimes. You have all these licensed parts from Corsair, ASUS, and Intel, yet you're stuck within the rigid "intended" gameplay loop that Epic Games and Spiral House designed. It's frustrating. You want to build a quad-GPU monster or maybe just use a case that isn't officially in the game yet. That's exactly where PC Building Simulator 2 mods come into play.
Most players think the game is unmoddable because it’s an Epic Games Store exclusive and lacks a Steam Workshop. They're wrong. While it's definitely harder to mod than the first game, a dedicated community has carved out ways to inject custom parts, bypass career mode grind, and tweak the lighting engines to make those RGB strips actually look like they aren't made of radioactive plastic.
The Reality of Modding on the Epic Games Store
Modding PCBS2 isn't as simple as clicking a "Subscribe" button. You're dealing with Unity-based files, which means you often have to use tools like Unity Assets Bundle Extractor (UABE) or specialized injectors. If you've played the first game on Steam, you're probably used to the "Bay02" or "Hemelix" mods that added hundreds of custom GPUs. In the sequel, things are a bit more technical.
The community mostly lives on Discord servers and Nexus Mods now. Because the game receives frequent updates that break file paths, you’ll find that a mod working on version 1.5 might completely crash your game on version 1.8. It’s a bit of a cat-and-mouse game. Honestly, if you aren't comfortable backing up your save files, you shouldn't even touch a modded executable. One bad file and your Level 30 career save is toast.
Custom Parts and the Quest for Realism
The biggest draw for PC Building Simulator 2 mods is, unsurprisingly, the hardware. Even with over 1,200 licensed parts, the game misses some iconic stuff. Where are the vintage 90s towers? Where are the weird, niche enthusiast blocks from Optimus Water Cooling?
Modders like those found on the PCBS2 Modding Discord have worked on importing custom meshes. It’s a painstaking process. You have to map out the "snap points" for every screw, cable, and plug. If the snap point is off by even a millimeter, the power cable will clip through the motherboard, and it looks terrible.
Why the Career Mode Unlocker is Essential
Let’s talk about the grind. PCBS2 forces you to repair endless dusty office PCs just to unlock the "fun" stuff like custom water cooling or high-end RTX cards. If you’ve already played the first game for 500 hours, you probably don't want to swap out broken sticks of RAM for fifteen hours again.

- Save Game Editors: These aren't "mods" in the traditional sense, but they are the most popular downloads. You can give yourself infinite money and instant level 30 access.
- Shop Unlockers: These mods modify the
Inventory.xmlor similar internal database files to make every part available from Day 1.
It’s basically a necessity for players who just want to use the game as a 3D design tool for their real-life dream rigs.
The Lighting and Visual Overhauls
The vanilla game has a specific "bloom" that makes everything look a bit hazy. Some people love it. I think it looks like someone smeared Vaseline on my monitor.
Visual mods for PCBS2 usually come in the form of ReShade presets. These aren't specific to the game's code but sit on top of the graphics API to sharpen textures and fix the color grading. A well-tuned ReShade can make the brushed aluminum on a Lian Li case look significantly more metallic and less like gray paint.
Some modders have even experimented with the GlobalSettings.json to increase the number of light sources the engine calculates. Warning: this will absolutely tank your frame rate. Even if you have a real-life RTX 4090, calculating 50 individual RGB LEDs in a virtual PC is a nightmare for a Unity-based sim.
Dealing with the "No Workshop" Problem
The lack of Steam Workshop is the biggest hurdle for PC Building Simulator 2 mods. On the Epic Games Store, there is no centralized hub. This has led to a fragmented scene. You have to go to Nexus Mods, then maybe a specific Discord, then maybe a GitHub repository for a specific tool.
It's messy.

But there’s a benefit to this "underground" feel. The people making these mods are true enthusiasts. They aren't just uploading 5-minute skin swaps. They’re building tools like the PCBS2 Calculator or custom fan curve adjusters that provide more utility than the base game ever intended.
Common Misconceptions About Modding PCBS2
People often ask if they'll get banned for using mods. Since it's a single-player game, Epic Games doesn't care. There’s no anti-cheat software looking for your custom RTX 5090 (fake) mod. The only danger is to your save file.
Another myth is that you can just drag and drop files. Nope. Most of the time, you are replacing the resources.assets file or using a mod loader like BepInEx. If you see a mod that is just a .png file, it’s likely a custom wallpaper for the in-game tablet, which is the "easy mode" of modding this game.
The Technical Side: BepInEx and C#
For the real tech-heads, the shift toward using BepInEx has been a game-changer. BepInEx is a plugin framework that allows modders to inject C# code into the game while it's running. This allows for "quality of life" mods that change how the game behaves, rather than just how it looks.
For example, there are mods that:
- Speed up the "unscrewing" animation (bless whoever made this).
- Automatically plug in cables when you place a part.
- Remove the "Incomplete Case" error so you can run a PC without a side panel.
These small tweaks make the simulator feel less like a chore and more like a creative playground.

How to Get Started Safely
If you’re ready to dive in, don’t just download the first thing you see. Follow a logical path to ensure you don't break your installation.
First, locate your game folder. It’s usually under Epic Games\PCBS2. Make a copy of the entire PCBS2_Data folder. This is your "oh crap" button. If the game stops launching, just move the backup back.
Next, check Nexus Mods. Look for the "Most Endorsed" section. You’ll see things like the Total Unlocker or various Part Expansion packs. Read the comments. If the last ten comments say "Game crashes on startup," the mod is likely outdated for the current version of the game.
Actionable Steps for Your First Modded Build
- Install a Save Editor: If you want to skip the grind, use a web-based save editor to bump your level. It's the safest way to "mod" without changing game files.
- Use ReShade: Download the latest ReShade and point it to the PCBS2 executable. Look for a "Realism" preset to fix the lighting.
- Join the Modding Discord: This is where the real-time help happens. The community is small but very active.
- Monitor Your Temps: Funnily enough, some mods can make the game so intensive that your actual PC will start sweating. Keep an eye on your hardware.
Modding this game is about taking control of the experience. The developers did a great job with the foundation, but the community is what keeps it alive for the hardcore enthusiasts who want to push the boundaries of virtual cable management and hardware aesthetics.
Start small with a simple wallpaper mod or a save edit. Once you're comfortable with how the file structure works, move on to the BepInEx plugins. Just remember the golden rule: always, always back up your saves before touching the internal assets.
