Provide extra facilities and advantages.
Warehouse Extension. Capacity of the Warehouse increases.
Land Management. Allows constructing any buildings on deposit cells.
Capital Transfer#
In order to transfer the Capital you need to study the science and it will become "charged". After that, click the icon of the "charged" science and in the pop-up box choose the city you want to become the Capital. When done, the Capital will be transferred to the specified city. The city level can be any, even first, but after the Capital transfer there will be 51 cells available in the city as it is supposed for the Capital. Maximum level of the Main Building will stay the same as it was before the transfer. In other words, you can get 51 cells in city with the Main Building of level 2, for example.
If you transfer the Capital from the initial city, 43 cells will remain there. If you transfer the Capital not from initial city, the primary number of cells will revert as it was before the city became Capital.
Buildings that have been constructed on extra cells in former capital will be removed. If in the former Capital you had buildings that are to be constructed in the Capital only (for example, the Diplomatic Corps) those buildings will collapse; you will be able to construct them again in the new Capital.
Army of the Ancients will stay in the city where they stood regardless of the Capital transfer.
Exchequer. Reduces troops basic salary.
City Expansion#
Each time, the science expands boundaries of the chosen city by 1 cell, but the limit is 43 cells in a city. The Main Building level doesn't change after Science studying increased the amount of cells in the city.
In order to expand city by 1 cell you need to study the science and it will become "charged". After that, click the icon of the "charged" science and in the pop-up box choose the city you want to expand. That moment a cell will be added inside of the specified city.
You can repeat the process as many times as many additional cells you want, up to the limit though. The science requires 25,000 of Science Points to get studied and "charged".
Production Technology. The science increases all resources production by certain %.
Military Drill. The science accelerates units training by certain %.
