In the game's words

How to use it

The Spy unit has Stealth ability and a bonus against mercenaries, Explorers, and War Chiefs. It's very useful in military campaigns, particularly as a relatively low-cost infantry unit. Another plus is that Spies can see other Stealth units.

History

For as long as there have been presidents and kings, governments have enlisted the aid of individuals for espionage. During the turbulent seventeenth and eighteenth centuries, spies were used by various governments to uncover secrets and identify opportunities for attack. Spies were known to use a variety of tools and technologies, such as invisible ink and secret codes. The fledgling government of the United States of America found itself embroiled in multiple assaults by loyalist spies - including secret messages sent to agents of the crown by William Franklin, Benjamin Franklin's own son!
