Spy (Age of Empires III)

The Spy is a unit available from the church starting in the Discovery Age. It can only be trained in the Age of Empires III expansions, and it is fairly expensive, and costs 2 population spots. 200 Gold is required to train a Spy. The Spy moves very quickly, and has the stealth ability, although it can be seen at all time by the enemies explorers, town centers and forts, however when activating the stealth abilty, spies move considerably slower.

The Spy is very good at scouting the enemy without them knowing, giving advanced notice on what they are building and when they will attack. The Spy has a very low base damage, but huge multipliers against explorers and mercenarys. The Spy can easily change the tide of a battle by coming in stealthed, and unstealthing and taking out enemy cannons and mercenaries.
