I was thinking ...a pop-up wall?
Just think of the possibilities it can provide.
Upgrading is possible just like normally upgrading your walls, and the max level you can upgrade depends on your TH, so you wont be surprise blocked by a lvl 10 wall with a lvl 5 TH, right?
2,3, or 4 avaliable depending on your TH, as usual.
Anyways, I think its a slick idea!
Give me your thoughts guys
