Evaluation
Sound of Drop - fall into poison - is a visual novel that launched on October 30, 2015 as a complete, self-contained story featuring 3 main routes and over 30 endings. Its only DLC is the official soundtrack, which released on December 4, 2015. After launch, the developer added Steam achievements in November 2015 and expanded the game's language options with French and Russian translations in August 2018 — both of which are maintenance and quality-of-life improvements rather than new story content.
The developer's more recent news posts (from 2023 and 2024) are promotional announcements for other games by the LYCORIS studio (UsoNatsu and Fatal Twelve), simply linking back to Sound of Drop as part of a catalog roundup. These posts do not announce any new content for Sound of Drop itself.
There is no unreleased DLC, no announced future content, and no developer statement indicating ongoing development of this title. The game launched as a finished product and has received no story content beyond its original release. The most recent substantive update to the game itself was the French and Russian localization patch on August 6, 2018.
