Evaluation

Full Metal Coffin launched on June 24, 2026. Prior to launch, on June 21, 2026, the solo developer (Titan) published a post outlining plans to support the game post-release with bug fixes and minor additional content, listing specific planned additions: a new enemy type, a new torpedo type, level difficulty selection, level scoring, new maps, and a potential new game mode. Two days after launch, on June 26, 2026, the developer posted an updated roadmap expanding on those plans due to the game's warm reception. The new roadmap commits to 2–3 stability patches followed by 3 large content updates, with each update's content to be announced publicly before development begins. The developer explicitly stated that after the third update, they will reassess next steps based on community feedback. A second stability patch shipped on June 30, 2026, delivering new settings, tweaks, and bug fixes — showing the developer is actively fulfilling this roadmap. The game is very recently released, actively being supported, and has a clear roadmap of upcoming content that the developer has explicitly committed to delivering.
