Evaluation

OPUS: Rocket of Whispers launched on February 8, 2018. Following launch, SIGONO released a substantial content update on June 25, 2018 that added new side quests (including a post-game mystery arc) and a director's commentary track with 16 recorded voice segments. This appears to be the last content update directed at Rocket of Whispers itself. Since then, SIGONO's news posts on this page have focused entirely on the studio's subsequent titles — announcing and releasing OPUS: Echo of Starsong (released September 1, 2021) and teasing OPUS: Prism Peak (announced January 6, 2023). Neither of these represents new content for Rocket of Whispers. The DLC list contains two items, both released: the original soundtrack (February 8, 2018) and an artbook with bonus world map (November 5, 2021). No unreleased DLC is listed. There are no developer statements announcing future content for this game, no roadmap, and no ongoing update cadence beyond the single post-launch content patch in 2018. The game launched and received one meaningful content addition, after which the developer moved on to new projects. Rocket of Whispers is a self-contained narrative adventure that was completed as a product as of the June 2018 update.

Evidence

A post-launch update added new side quests expanding on the game's mystery and a 16-track director's commentary. This is the last update to the game's content.

About this game

“By this rocket, we return them to the cosmos.“

Travel across a world of ice and snow, through burned down ruins and treacherous peaks, to launch a rocket that will reach the stars.

“Once we fire the rocket, will these ghosts finally leave me?” Asked the man.
“Of course. Our goal, after all, is to return them to the cosmos” The witch replied.

Throughout the game, you will play as two survivors of an apocalyptic plague. Help them achieve the unimaginable of building a rocket, so they can return the deceased to their cosmic homeland through the ancient tradition of space burials.
