Treason is a technology in Age of Empires II available at the Castle upon reaching the Imperial Age. Once researched, it reveals all enemy Kings for a short time, and their location at that time is shown as explored through the fog of war. It is only available in the Regicide mode and replaces the Spies technology. Treason is the only technology in the game to be temporary and researchable multiple times. It is researched almost instantly.

Treason is one of the most important technologies in Regicide games as it tells players where to mount their offensives and allows them to plan ahead.

The Huns can research Atheism, which reduces the cost of Treason by 50%.

Trivia[edit | edit source]

  • Treason is a crime against the state. In the context of the Middle Ages, treason is closely linked with kings since most governments in the Middle Ages were monarchies.
  • Apart from Loom and the advance through the Ages, Treason is the only technology not to be affected by the Chinese civilization bonus, which reduces the cost of all other technologies (including Spies).
