“While the romanticism in its cosmic quest for Earth is charming alone, it is the growth we share with the characters aboard the ship that truly shine.”
IGN Japan

“Opus: The Day We Found Earth is a lovely little game. At more or less the length of a movie, it’s not going to keep you entertained for the weekend, but it’s perfect for a quiet night in.”
Nintendo Life

“...Through the developer's excellent and careful pacing, the emotional impact of this game is no less powerful than many triple A epics.”

About This Game

The multi-award-winning adventure game from SIGONO is now available on Steam! Featuring a heartwarming story written by the team's IMGA-nominated writer.


In year 160000 of the Galactic calendar, mankind has reached far across the stars from millenia of migration. The knowledge of Earth's existence has been lost to time, and is now a distant myth. But centuries of genetic engineering is driving the gene pool towards a dead end, and only samples of our earliest DNA may save us from extinction. And so, with the fate of mankind resting on its shoulders, a lone spaceship embarks upon a journey to rediscover our origin.

"A robot without a goal is nothing more than a calculator. So, listen up... Your goal, is to find Earth. Do we have a deal?"
- Dr. Lisa

"We have a deal… Emeth will find Earth!"
- Emeth, Lisa's creation

Help Emeth fulfill a centuries-old promise with his creator in this story-driven puzzle adventure, as he realizes a greater purpose inside his tiny mechanical heart.
