New Development Roadmap

This update marks the first step toward greatly expanding the combat structure and strategic depth of Master of Piece.

We will continue to gradually add new battles, Commanders, content, challenge elements, and more as we further improve the game throughout Early Access.

You can check the image below to see the main update directions we are preparing for the rest of 2026.

Please note that some items included in the roadmap are still in development or under review, and their release timing or details may change depending on the development status.

We hope you enjoy developing your own strategies on the newly transformed battlefield introduced in this update. Thank you.
