Experience Tactical Card Battles Firsthand!

The game's standout feature is its 'real-time tactical card battle' system, supporting up to 4 vs. 4 matches. Despite being a card game, players on each team act in real time, using cards dynamically.

The demo allows players to enjoy the 'Mission Mode,' where they can fully experience the game's tactical card battles. Unlike multiplayer matches, this mode lets you battle against CPU opponents at your own pace, with no time limits. Dive into a strategic card battle where every decision determines victory or defeat.

※ Please note: Multiplayer mode is not available in this demo version.

Practice your card battle skills against NPCs. The difficulty is finely tuned to provide a challenging experience.

Mission Mode features roguelike progression. While card upgrades carry over between runs, so do resource depletions such as health, so strategize carefully.
