Industrial, Modern, Information, and Orbital Earth
How milestones 0.41–0.50 extend the same civilization rather than replacing it.
modern_and_orbital_earthIndustrial power
Coal, Oil, electricity, factories, mechanized extraction, pollution, industrial districts, Steel, Fuel, and Components create connected production chains with efficiency and environmental tradeoffs.
Oceans and aviation
True ships and aircraft use direct map orders. Fishing Fleets work fishing nodes for Food, cargo and landing craft carry troops, warships and combat wings fight, Ports unlock ocean trade, and distance-based fuel keeps global mobility powerful but expensive.
Information and global institutions
Digital networks, cyber operations, automated cities, corporations, congresses, global resolutions, shared research, observation, and collective defense make information and cooperation strategic resources.
Space remains attached to Earth
Space centers, satellites, reusable launches, orbital research, monitoring, and station modules improve Earth. They do not yet open the later FTL management and alien-world colonization game.
Modern projects are catalogs, not hidden rules
The Milestones, Projects, Assets, Corporations, Contracts, Resolutions, and Legacy Objectives pages list every definition and requirement.
