How to Make an Atomic Bomb in Your Garden Crafting Guide
Updated 2026-06-13

Understanding the Crafting System
The crafting system in How to Make an Atomic Bomb in Your Garden is the core of the entire game. Unlike traditional simulation games, you don't just click a button and wait. You must actively gather resources, manage your secrecy meter, and assemble components in the correct order. This guide will walk you through everything you need to know about how to make an atomic bomb in your garden crafting.
Your journey begins with a simple workbench in your backyard shed. As you progress, you'll upgrade this workstation to handle more complex components. The game's crafting is divided into three main phases: Resource Gathering, Component Fabrication, and Final Assembly. Each phase requires specific tools and materials that must be acquired without raising suspicion.
Important: Your Secrecy Meter is your most critical resource. If it fills completely, neighbors or federal agents will intervene, ending your run. Always balance crafting progress with stealth.
Essential Tools and Workbench Upgrades
Before you can start crafting, you need the right tools. The game offers a progression of workbench upgrades that unlock new crafting possibilities. Here are the essential tool tiers:
| Tool | Required Level | Purpose |
|---|---|---|
| Basic Toolkit | Starting | Disassemble household electronics |
| Precision Welder | Level 3 | Join metal components |
| Chemical Mixing Station | Level 5 | Create specialized compounds |
| Isotope Separator | Level 8 | Process rare materials |
To upgrade your workbench, you'll need both money and specific parts. Check our upgrades guide for detailed material lists. The Precision Welder, for example, requires a broken microwave transformer and three copper coils.
Pro Tip: Visit the scrapyard at night to find rare components without attracting attention. The resource management guide has a full map of safe looting spots.
Step-by-Step Crafting Process
Follow these steps to successfully craft your atomic device. Each step must be completed in order, or you risk a catastrophic failure.
Step 1: Gather Base Materials
Collect lead, steel, and copper from construction sites and electronics. You need at least 50 units of each before moving to fabrication.
Step 2: Fabricate the Core Casing
Use your Precision Welder to shape the steel into a containment sphere. This requires the "Metalworking" skill unlocked at Workbench Level 4.
Step 3: Create the Trigger Mechanism
Assemble the triggering device using rare earth magnets and a high-voltage capacitor. These components are only found in specific locations.
Step 4: Process the Fissile Material
This is the most dangerous step. Use the Isotope Separator to refine uranium ore. Each attempt generates significant heat and radiation, increasing your Secrecy Meter.
Step 5: Final Assembly
Combine all components in the correct order: casing first, then fissile material, then trigger. Use the mechanics guide for exact positioning instructions.
Rare Components and Where to Find Them
Some components cannot be crafted and must be found in the world. These are the most critical items for completing your project. The walkthrough provides detailed location maps.
| Component | Location | Risk Level |
|---|---|---|
| High-Voltage Capacitor | Abandoned power station | Medium |
| Rare Earth Magnets | Electronics recycling center | Low |
| Beryllium Reflector | University research lab | High |
| Neutron Source | Hospital radiology wing | Very High |
Each location has its own security measures. The secrets guide reveals hidden paths that bypass most guards. Remember to wear a disguise when entering high-risk areas.
Managing Your Secrecy Meter
The Secrecy Meter is displayed as a progress bar in the top-right corner of your screen. It increases when you:
- Make loud noises (grinding, welding)
- Buy suspicious materials in bulk
- Get caught by neighbors
- Leave evidence at crime scenes
To reduce your Secrecy Meter, you can:
- Bribe neighbors with small gifts
- Plant false evidence to mislead investigators
- Lay low for several in-game days
Warning: If the Secrecy Meter reaches 100%, the game enters "Lockdown Mode." Federal agents raid your property, and you lose all progress. Save frequently and always have an escape plan.
Common Crafting Mistakes to Avoid
Many new players fail because they rush the process. Here are the most common errors and how to avoid them. The beginner tips guide covers additional strategies.
Advanced Crafting Techniques
Once you've mastered the basics, you can optimize your crafting process. The progression system guide explains how to unlock these advanced techniques.
Parallel Crafting: With a high-level workbench, you can fabricate multiple components simultaneously. This requires careful timing and resource management.
Stealth Assembly: Certain upgrades reduce the noise of your crafting station. The "Sound Dampening" modification cuts noise by 60%, allowing daytime work.
Material Substitution: Some rare materials can be replaced with more common alternatives. For example, tungsten can substitute for depleted uranium in non-critical components.
Did you know? The game's crafting system is based on real physics principles, though heavily simplified. The lore explained guide dives into the science behind each component.
Final Assembly Checklist
Before attempting the final assembly, ensure you have completed all prerequisites. The endings guide explains how your choices affect the outcome.
- Workbench upgraded to Level 8
- All four main components fabricated
- Secrecy Meter below 30%
- Protective suit equipped
- Emergency exit plan ready
- At least three save files backed up
Once you're ready, proceed to your workbench and select "Final Assembly." The game will play a short animation, and then you'll see the results of your hard work. Congratulations on mastering how to make an atomic bomb in your garden crafting.
