Evaluation
Meridian 157: Prologue released on December 9, 2020 as the first entry in the Meridian 157 series. The store description labels it explicitly as "the first in a series of point-and-click puzzle adventure games," indicating it was always intended as a standalone prologue chapter rather than a live-updated product. There is no DLC listed, no roadmap, and no developer announcements about future content for this specific title. The only developer communication on record is a maintenance patch on March 31, 2026, which addressed minor bug fixes for Windows and MacOS — consistent with routine upkeep of a finished game. The game launched as a complete, self-contained episode and has not established any post-launch content update pattern. It is best understood as a finished product that serves as the introduction to the broader Meridian 157 series.
