About
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.

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 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.

Reviews
Игра прикольная и даже информативная, но есть минусы с сохранениями. Можно сохраниться только между этапами, поэтому приходится выделять чути ли не под 2 часа чтоб закончить хоть частично хотя бы второй этап Игру вернул, к сожалению у меня нет возможности безвылазно и без внешних факторов иметь 2 часа минимум свободного времени
i will do this thanks for the advice
highkey a very good game i recommend to anyone who wants time to go by fast and likes to build things
Played it, beat it. Its like many other sim games however no fun mechanics. just tedious tasks. Would never replay it. Would not recomend.
