The game is an identity concealment game in which players are divided into two camps, the agent camp and the spy camp, and must take action to achieve their respective victory conditions.
The purpose of the spy is to disrupt the activities of the agents and eliminate them all.
Agents report suspicious persons to each other in meetings and sometimes vote to expel them. The agents win if they dispose of all the spies or complete Operation C. However, if all the agents are killed before completing Operation C, the spies win.
