About this game
《Master of Piece: Prologue》is a free prologue version of 《Master of Piece》, a deck-building roguelike game inspired from board games, offering simple yet deeply strategic gameplay. Recruit an expedition team of mercenaries, and embark on a journey to uncover the secrets of a world shrouded in dark mist.
Wishlist the full version to play the complete Mercenary-deckbuilding Game!
The full game is scheduled to release in November 2025, as Early Access.
Optimize your strategies, Deploy your mercenaries, and fight the battles to achieve victory. Strengthening and combining mercenaries’ unique traits are essential to creating powerful synergies and combinations, which will increase your chances of completing this perilous journey.
Combat
Deploy one mercenary unit per round to the battlefield and engage in combat. Once combat begins, mercenaries act in order based on their speed. Devise your best next move, given your current situation.
With simple controls and a straightforward system, anyone can easily fathom the basic mechanics of the game. However, mastering and optimizing the variable combinations of mercenary traits, relics, and commander’s abilities will demand a deep and complex understanding. Easy learning, but deep, challenging gameplay at the same time!
Strategic Combinations
Build your team of mercenaries, not cards. Mercenary units can be enhanced and modified in various ways along the journey, offering new strategic combinations every time you play.
Explore different journeys with 140+ mercenaries and traits, 80+ relics, and 400+ card events.
Discover diverse combinations, build support facilities in campsites, make the ultimate expedition team of your dream.
Every new game you play will be perceived differently from the previous experience, with diverse events and randomly generated paths & enemies. 120+ types of mercenaries, 80+ types of relics, 14+ types of building events, and 400+ card events will contribute to creating an infinitely replayable game.
The Purpose of the Prologue Version
Since launching the demo in March, over 10,000 players have downloaded our game, and many have provided valuable feedback to various parts of the game.
Thanks to all the feedback we’ve received since the demo’s release, we’ve been able to improve many aspects of the game. We’re truly grateful for the opportunity to communicate with our players and see the game make progress because of it.
Recognizing how essential user feedback is to creating a quality gaming experience, we’ve decided to boldly implement features that, if not for the Prologue, would have been considered only internally—and observe how players respond.
The Prologue will function as a kind of test, helping us determine which features should make it into the final version based on community feedback.

Aside from the Demo that we have released in March, here are the new features that are added in this Free Prologue Version:
New region - The Blazing Sands
The 2nd region will be open to play in the Prologue!
