About OPUS: The Day We Found Earth

DOES EARTH REALLY EXIST?

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.

About OPUS: Echo of Starsong

"I will claim the starsongs, and bring honor to the clan."

    Hi, the new link is the same old link torrent.
    OPUS: Echo of Starsong is “v1.8.6 r6 bda04” and not “v2.5.6 18”
    Thanks! for all games

    1. freegogpcgames

      Hello Trex, sorry about that we’ve mess up the link (forget to change). Added the real link and hope that it works now.

  2. User2817

    It seems the download is broken? qBittorrent is stuck on loading metadata forever. Is there a way to fix this?

    1. freegogpcgames

      @User2817, we manage to download this and now we are seeding it. Please be patient when downloading sometimes seeders turnoff their system.
