-Civil Defense
-Commercial Dock
-Stock Exchange

WONDERS of the WORLD
-The Internet

BUILDING
-Airfield
-Outpost
-Radar Tower


Thanks

Civil Defense adds an additional 50% defense to cities. Can only be built in cities with a Barracks.

Commercial Docks add 1 gold to every water tile that is already producing gold. City has to have a Harbor to build the Commercial Dock

Stock Exchange increases tax output in a city 50%. Requires a Bank.

The Internet puts a Research Lab in every city on the continent and sparks a Golden Age if you haven't already had one yet.

Outposts push back the Fog of War. Consumes the Worker.

Airfields allow you to rebase, airlift and airdrop at a forward base where you don't have a city with an Airport. Available with Flight. Consumes the Worker.

Radar Towers add a 25% combat bonus to all units within a 2 tile radius. Available with Radio. Consumes the Worker.
