The third and final tab included in the Age of Empire Online Technology Tree is the Utility Tab.
It contains upgrades for support units, and upgrades that can boost the stats of combatant units, such as armor or damage.
It is also the tab that provides upgrades for towers and marketplaces.
To unlock new upgrades in the Utility Tab, AoEO players need Tech Points, and a palace in the Capital City.
The Utility Tab is similar to the Economy Tab and the Military Tab, but varies from one civilization to another.
In other words, the Utility Tab available to the Greek civilization is different than the one that can be accessed by the Egyptian civilization.
In the following game guide, Age of Empire Online fans can find all upgrades they can acquire through the Utility Tab.
The guide explains how many points are needed for each upgrade, and how these upgrades affect the players units and buildings.
