You are spies, each with a network of agents completing missions in up to 12 European cities for your employers. With your agents help, you must create a network of secure connections between cites. Your spy will travel through this network as efficiently as possible to complete your mission objectives. Or send your agents to your headquarters to plan new missions.
Be careful – if you take on too many missions at the same time, your network will dwindle and your ability to reach new cities quickly will be diminished. Only the most efficient and clever player will become the spy master at the end of the game.
