About Opus: The Day We Found Earth
Opus: The Day We Found Earth is a story-driven puzzle adventure about Emeth, a small robot sent to rediscover Earth. In the Galactic year 160000, humanity has spread across the stars through millennia of migration, and knowledge of Earth has faded into myth. Centuries of genetic engineering are pushing the human gene pool towards a dead end; samples of humanity’s earliest DNA may be the only way to prevent extinction.
Emeth’s mission
Emeth is created by Dr. Lisa, who asks him to find Earth. You help him fulfill a promise made to his creator centuries earlier as he discovers a greater purpose. The journey follows a lone spaceship searching for humanity’s origin.
Explore and investigate
You travel through a starscape of stars, planets and nebulae, operating a space telescope to scan stars across the sky. You also search the spaceship for items that reveal the crew members’ pasts and the history of the centuries-old mission.
Music and story
The game features over 20 soundtracks as you explore space, alongside a science-fiction story about finding Earth and the fate of humanity.
