The text describes a suspenseful online game where up to 12 players can compete against each other. The objective of the game is to uncover the murderer among the players and expel them from the mansion. Players must carefully listen to each other's statements and analyze their actions to identify the murderer. The game features an innovative accusation system where players can accuse the murderer, but they must be careful not to accuse the wrong person, as they may be expelled instead. Completing missions and earning points are also important aspects of the game.

The game is a chat-based mystery suspense game where players are divided into different factions and compete against each other. The prologue sets the stage on a deserted island where the owner of the mansion is killed at a party. The murderer's goal is to kill all members of the owner's family, while the family faction aims to uncover the murderer and escape from the island. The game consists of three parts: discussion, accusation, and night actions. In the discussion part, players chat with each other to narrow down the suspects. In the accusation part, players can expel the murderer by accusing them and revealing the murder weapon. In the night actions part, players can move to different rooms to search for items or escape, but they must be cautious of the murderer's actions.
