Evaluation
Meridian 157: Chapter 3 launched on July 29, 2021 as the explicitly described "final and longest chapter in the Meridian 157 storyline" — the store description markets it as a narrative conclusion, not a starting point for ongoing content. The developer has never announced DLC, expansions, or any additional content beyond the base game. There are no unreleased DLC listings on the store.
Post-launch activity has been limited to maintenance: two small bug fix patches in the days following launch (July 31 and August 14, 2021), and a single feature patch on March 31, 2026 that added a quality-of-life navigation improvement and fixed platform-specific issues. None of these patches introduced new story content or signaled plans for future content.
This game launched as a complete, self-contained conclusion to its series, and all developer communications are consistent with that — it shipped finished and has only received upkeep patches since.
Evidence
Store description explicitly markets the game as 'the final and longest chapter in the Meridian 157 storyline' and 'this final adventure,' indicating it was designed and shipped as a complete, standalone conclusion.
A maintenance patch added a right-click navigation feature and fixed camera/cinematic and platform-specific bugs. No new content introduced.
