OPUS: Echo of Starsong

OPUS: Echo of Starsong is a science fiction adventure from the Taiwanese studio SIGONO. The story combines a long journey through a star system scarred by war with dialogue, exploration and small sound puzzles. At its centre are Jun and Eda, whose shared search for the mysterious Starsongs shapes the rest of their lives.

The PC version came out at the end of August 2021. The Nintendo Switch version followed on May 11, 2022 as the Full Bloom Edition with new voice acting. Xbox One came out on August 25, 2022, iOS on November 17, 2022 and PS5 on February 4, 2026. An Android release restricted to mainland China has been available since July 2024.

The game is natively available for PC, Nintendo Switch, Xbox One, PlayStation 5 and iOS. The Android version is available through the Chinese TapTap store. On Xbox Series X|S, the Xbox One version is playable; there is no separate native Xbox Series version as a result. A PlayStation 4 version is not confirmed as a native release.

You travel with a small crew through a star system full of asteroids, trading posts and old facilities. Between narrative encounters, you decide which destinations you can reach with your limited supplies. The game world is opened up via a star map, while short exploration sections and dialogue drive the story.

OPUS does not focus on fast reflex combat. Decisions on the journey, discovering new places and the connections between its characters are in the foreground.

For Windows, the game requires at least an Intel Core i5-2300 or AMD FX-4350, 4 GB RAM, a GTX 570 or Radeon HD 7850, and 4 GB of storage. SIGONO recommends, among other things, 8 GB RAM and a GTX 950 or Radeon RX 560. Steam also lists a macOS version.

The outcast Jun searches for the valuable resource Lumen to restore his family's honor. Eda can perceive the sound of special asteroids and therefore becomes the decisive companion. Their shared journey leads them through the aftermath of a long-running conflict and focuses on love, loss and memories.

The mysterious Lumen asteroids are a major reason for the conflicts in Thousand Peaks. Eda hears their special vibrations, which allows the crew to find places that remain hidden to others. Lumen is not only a target of the treasure hunt but part of the story about the consequences of power and exploitation.

The search leads to temples and locked gates. To move on, Jun matches musical patterns with the sound of the star songs. The tasks are deliberately easy to access and form short breaks between exploration and dialogue.

On the map, you choose between asteroids, space stations and settlements. Along the way, unexpected encounters with traders, authorities or stranded ships can occur. Sometimes you have to weigh whether to spend resources or take on extra risk.

Jun and Eda meet many residents of Thousand Peaks. The characters' personal stories show how the former war has changed their everyday lives. Besides the main story, further backstories and side quests can be discovered.

Full Bloom adds voiced dialogue to the original version. The Nintendo Switch version was released directly under this name; the revised version later became available on PC as well. The story and the musical puzzles remain the foundation of the experience.

Steam offers on-screen text and subtitles in English, Japanese, and Simplified and Traditional Chinese. The new voice acting in the Full Bloom Edition is available in Japanese and Chinese. German text is not listed on the mentioned stores.

According to SIGONO's App Store description, the main story is designed to take about ten to twelve hours. Additional character backstories and side quests can add another two to five hours. Depending on how thoroughly you explore the locations, the actual playtime varies.

OPUS: Echo of Starsong is designed for one player only. Co-op and competitive multiplayer modes are not part of the game. The narrative structure can be experienced without time pressure.

The iOS version is available on Apple's App Store for iPhone and iPad and also supports Apple TV. On Android, the adventure was released in mainland China on Jul 26, 2024 on TapTap. An international Google Play version has not been confirmed.
