Engineering is a removed tier three technology that unlocked the Destroy ability, which removes a building or ruin at no cost, and the Guard Tower, an unmovable unit. Engineering and the Guard Tower were planned to be released in the "Power" update but were scrapped before release because they slowed the pace of games. The Destroy ability is now unlocked by Chivalry.
Diplomacy currently occupies the place of Engineering in the technology tree.
