anyone know how to make a game similar to civ5 or beyond earth in this engine?
if you do that would be a big help
Hexed/Tiled map is a little tricky process.However Epic has an example project about it. I think it was named Turn Based Strategy Game on Content Examples section. You can start there.
create your AI architecture in C++ ( some help: Amit’s Game Programming Information ), create your procedural map generator in UE4 BP or C++, release, ???, profit! 
advanced turn based tile toolkit on the marketplace seems good but if you want to make your own hex grid i think you need to do that in C++ or some other programming language. iv found a few examples of how to make hex grids on google in C++ but i dont know how to use them with unreal yet.
the link I shared contains nice description of different grid systems including hex. that package you mentioned also features hex grid.
