# Building & Upgrading

You will need a vision so brilliant that it inspires a whole population. Build a city that your people truly worship, a city they will defend with conviction. Every BOFY city has 22 squares for your buildings, which will act as the supply chain for vital products that will be needed for your city to strike attacks or stand strong against invaders of the city.

Buildings are the main instrument for any resource or production in the game. Every building level adds additional perks for the building or increases its capacity.
