Need more Age of Empires Online
inventory space? Then the "Empire Vault" is the feature you need!
The Empire Vault is a shared Inventory for all of your civs on your current realm. It comes with 4 shared Inventory slots, and can be expanded it to up to 240 slots with Empire Points. With the Vault open, you right-click items to add them and right-click Vault items to send them back to your inventory. The inventory can be filtered by item type (All, Gear, Materials, Advisors, Recipes, etc.).
The Empire Vault can be accessed from its button attached to the minimap near your regular Inventory on the Capital City UI. It can be purchased right there or from the Empire Bazaar. You expand its capacity from within the Vault itself.
The "Empire Vault" will become available in the upcoming Anniversary Update.
