Satellite Odyssey: Prologue

Satellite Odyssey: Prologue is explicitly described as the first installment in the Satellite Odyssey series — a standalone, approximately one-hour story-driven adventure. The game launched on August 30, 2024 and received several post-launch patches adding a second ending, a new questline, horror elements, improved localization, and professional voice acting. The developer has been transparent that this title is a prologue — a self-contained entry meant to introduce the series — and not a live-service or ongoing content product. The developer's focus has since fully shifted to the next game in the series, Satellite Odyssey: Jupiter, which was formally announced on November 27, 2024 with a trailer. As of April 12, 2025, the developer confirmed they are "actively working on the next installment" while noting they have continued to improve Prologue with localization updates. The Prologue itself has no announced future content — improvements made since launch (voice acting, Chinese localization) represent quality-of-life polish rather than new story or gameplay content. With no unreleased DLC, no roadmap for further content in Prologue, and the developer's stated attention directed at Satellite Odyssey: Jupiter, this game's content is complete. The completion date is set to April 12, 2025, reflecting the last substantive update (professional English localization and Chinese translation) that rounded out the game's final form.
