How to Make an Atomic Bomb in Your Garden Secrets Guide

Uncovering the Game’s Hidden Secrets

How to Make an Atomic Bomb in Your Garden is packed with clever secrets that reward exploration and careful planning. While the main objective is clear—assemble a functional atomic bomb in your backyard—the path is littered with hidden interactions, rare components, and alternate endings. This guide reveals the most valuable secrets that most players miss on their first playthrough.

Understanding these secrets can drastically reduce your playtime and help you avoid unwanted attention from neighbors and federal agents. Whether you are looking for a specific rare part or trying to unlock a secret ending, this guide has you covered.

Secret Rare Component Locations

The most critical secret in the game is the location of rare components. These are not marked on any map and often require solving small environmental puzzles to access.

Key rare components and their hidden locations:

• Plutonium Core: Found inside the abandoned storm drain behind the old mill. You need a crowbar and a flashlight to navigate the dark tunnels.
• High-Grade Detonator: Hidden in the neighbor’s greenhouse. Wait until night and use the garden hose to create a distraction.
• Uranium Rods: These are buried in the cemetery under the third grave from the left. Dig at midnight for the best chance of success.
• Government Schematics: Tucked away in a locked briefcase inside the post office. Pick the lock or find the key in the mayor’s office.

How to Evade Neighbors and Agents

Secrecy is everything in this game. If your neighbors or federal agents become suspicious, your project will be shut down. Here are the top secrets to staying under the radar:

Unlocking Secret Endings

The game features multiple endings, some of which are well-hidden. Your choices and actions determine which ending you get. Here are the known secret endings and how to unlock them:

The “Peaceful Detonation” Ending: Assemble the bomb but choose to detonate it in an empty desert instead of your garden. This requires stealing a truck and driving the bomb out of town.

The “Government Contract” Ending: Instead of detonating, contact the government and sell your knowledge. You must have all schematics and at least one complete bomb assembly.

The “Alien Intervention” Ending: Collect three mysterious meteorite fragments hidden around the map. Combine them with the bomb to attract an alien spacecraft.
