Modules are special components that can be installed into your base's cores in the Auxiliary Facility. Modules can be collected from various events, installed and upgraded to provide bonuses to your base. Your cores can provide powerful abilities that are activated from the right side shortcut menu (Economy and Fleets menu) in a special tab there. Using these abilities requires the item Ether Energy. Modules and Ether Energy will be found in events, packs and other places!
