Infrastructure Technology
Available To: All Major Factions
Prerequisite: Globalization
Difficulty: 50
Unlocks: Tier 2 City Centers
Required By: Military Base Automation or Next Generation of Force Spawner, Megalopolises


This technology unlocks the Tier 2 upgrade of the City Center structure, which increases both population growth rate and tax income. This upgrade doubles the Center boost from three to six percent, and is worth investing in, but the high upgrade cost and population required to staff these structures will remain an issue, particularly for new empires. As a prerequisite Technology it leads to other useful techs later, in particular Orbital Defence System, so all players will want to unlock this at some point.
