Hi there,

First, some big news: development of OPUS: Prism Peak is complete. Ren and Eugene's journey is ready.

We're now in the final stretch of cross-platform compatibility testing and certification. To ensure a smooth, simultaneous launch, the release date for Nintendo Switch, Nintendo Switch 2, and Steam has been moved to April 16, 2026.

We know the wait hasn't been easy, and a few more weeks was not what anyone wanted to hear. But it means we can put this in your hands exactly as it should be.

We thank you for staying with us through this final stretch.

See you at the peak on April 16.

Hi there,

How have you been?

Since the journey of Echo of Starsong ended, we’ve been completely buried in the world of Prism Peak. Every time we think of the incredible warmth and support you’ve shown us along the way, it reminds us that all those long nights of development were truly worth it.

Today, we’re so excited to finally share some news with you: OPUS: Prism Peak will officially launch on March 26, 2026, on Steam, Nintendo Switch, Switch 2.

To celebrate this milestone, we’ve just released a brand-new trailer featuring music by our amazing partner, Kevin Penkin (Made in Abyss). We still remember how we felt when we first heard his music bring our world to life, and we couldn't wait to share that feeling with you.

Watch the Trailer here:

The road to the peak might feel a little bittersweet, but remember, you’re never alone. The spirits of the mountain will be there to part the mists and guide Eugene and Ren home.

Thank you for being part of the OPUS family. We can't wait to see you at the peak!

03.26.2026. See you then!

Warmly,

SIGONO
