Evaluation

Mech Builder launched on July 16, 2024 and has since received a steady stream of post-launch content. A free update on November 30, 2024 added 10 new models. Three paid DLC packs then followed at regular intervals: DLC 1 (February 4, 2025, 15 models), DLC 2 (April 18, 2025, 15 models), and DLC 3 (September 30, 2025, 15 models). All three DLC packs are now released, and no further DLC is listed on the store. The most recent developer news (June 15, 2026) is an announcement for an entirely separate new game — "Click Build Repeat" — an incremental gunpla game releasing in July 2026. A May 2025 post also teased a 3D sequel called "Mech Builder 3D." Neither of these constitutes a commitment to additional content for the original Mech Builder. With all announced and listed DLC shipped, no unreleased DLC on the store, and the developer's attention now clearly directed toward new projects, the original game's content appears complete as of the DLC 3 release on September 30, 2025.
