About How to Make an Atomic Bomb in Your Garden

It’s a quiet Sunday morning. You're relaxing in your backyard when it suddenly hits you:
You need to build an atomic bomb.
Naturally.

In this absurd single-player simulation, your peaceful suburban life takes a wild turn as you attempt the most questionable DIY project imaginable. Building a nuclear bomb in your backyard might not be the hardest thing you’ve done but it’s definitely the weirdest.

What You’ll Be Doing

To complete your creation, you’ll need to:

  • Raise funds via a chaotic mini-game that tests your charm and hustle.

  • Go shopping: Bid on auctions and scour regular online stores for those oddly specific blueprint parts.

  • Do the math: Turn everyday household objects into actual atomic equations.

  • Extract critical materials from totally unrelated household items.

  • Assemble everything with precision... or at least, something close to it.

  • Handle your nosy neighbors, who are just a bit too curious.

  • Avoid IRS scrutiny, because spending your fundraiser money on plutonium raises red flags.

  • Manage your stress using strange and increasingly unhinged coping mechanisms.

The Goal

The game is split into three major stages of building, each bringing its own unique challenges that will test your patience. Complete all three to finish your project ideally without any accidents along the way.

Disclaimer:
Some elements in this game are inspired by real-world nuclear formulas. Do not try this at home. Do not be inspired. Seriously.

Estimated Playtime:
30–183 minutes
