Tips for building a mobile online base building game

Hi everyone,

I am about to start a new project but it is already making me crazy :slight_smile:

In my game there is a big (maybe unlimited) map but kind of like a chest board with multiple areas. This map is not very detailed (you will se mountains and so on with low detail from a great distance). Everyone can move between this areas and go onto a detailed map which will be better detailed. On this map they will be able to do stuff, but not everyone will be able to see everything just a group of players.

So far so good. I’ve been searching for similar questions but no one answered the questions.
How would I build such a game with Unreal Engine? Since the server only supports one map I thought of one map with hidden objects (which will make the map pretty messed up due to all the objects). But this way I would be able to use Unreal Server and save a whole lot of time?

If in other case I would want to make a own c++ server, is it possible to write a custom communication with a Unreal Game Application.

If i left open any questions I’m sorry. :slight_smile:
For any reply I would be very grateful since I am stuck and don’t know how to start.
