Armory level4? Wooden tree house?

[bassbone1]

How do you get your armory to level 4? Or is this for a future update or expansion of the app?

Does anyone know what looks like (for lack of a proper name) the wooden tree house is for and how you activate it?

Thanks in advance

The Armory can only be upgraded to level 3 currently. Also, the "wooden tree house" is not accessible yet. You can look forward to it in a future update. :)
