サイレントサイン is a mobile app adaptation of the popular board game "Shadow Hunters." This new genre of "silent werewolf" game challenges players to communicate without words and engage in thrilling battles.

In this game, players are divided into three factions and compete against each other to achieve victory. The "Shadow" faction brings darkness to the world, while the "Hunter" faction is dispatched to fight against them. The "Egoist" faction deceives both sides for their own ambitions.

Amidst the fog where no one knows who is friend or foe, players must combine skills and items to predict the intentions of their enemies and allies, all without uttering a single word. With unique character skills, players can turn the tide of battle, while special abilities from helper characters provide an edge. Master the game by building your own deck and grasping the situation on the battlefield.

The game also offers a captivating story mode, where new characters are introduced to unravel the mysteries behind the death game of "Shadow Hunters." Engage in a devilish game to prove the connection between the death game and the deaths of your friends, and uncover the truth in a story reminiscent of a mystery novel.

For those who prefer competitive battles, the match battle mode allows players to enjoy the death game against each other. Utilize your unique character skills and strategic thinking to compete without uttering a single word.

サイレントサイン is a free app, with some optional in-app purchases available.
