Medieval Support Base

A Medieval Support Base is a building in Survival 303.

Overview
The medieval support base is unknown to most people. Its most essential use is that a medieval wall could be built on top of it, as well as a medieval gate. It could also be stacked on top of each other. This will stop a lot of raiders from breaching your perimeter, especially those with bombs. However, it is hard to place a functional gate on top of a base. The tower version is the Medieval Corner Base.
