There are several types of buildings. All these buildings can be captured and used by himself.
I will here describe only two building types, as all the other buildings are to be used in the same way.
To enter one of the buildings, do a double-click on the entrance of the building.
In the depot all units standing in this building are displayed.
Do a double-click in a unit to move them out of the building.
If you click on a unit single time, unit informations are displayed. You can repair a unit using the repair button (broken first-aid-cross).
In a factory you can repair units too, and now you can create new units.
To create a new unit, press on the symbol of hammer/tank, and select a unit to produce. The new unit will be displayed in the list of units and can be used next round.
The ability to produce and/or to repair is limited. This always depends on the number of crystals. How many crystals the respective building have, can you see in the top right of the building view ( Blue Crystal ).
Production of water units is only possible in harbor buildings.
