Welcome to THE AGENCY. We appreciate your service to our country. This is your initial briefing.
You will receive your encrypted messages through a shortwave radio station known as Numbers Station: Alpha. You have been provided the frequencies in the HF band to access this station.
As you practice your spycraft each day, you will learn to crack messages, travel the world, and complete top secret missions.
A spy can never be too cautious. There will be danger.
