An Xbox version of real-time strategy Age of Empires 4 looks like it’s currently in testing within Microsoft.
The file in question references Cardinal, Microsoft’s internal codename for Age of Empires 4, and is the first to reference the Xbox platform.
The console port was apparently sniffed out by Twitter user ALumia_Italia (thanks, VGC), after seeing a new file uploaded for internal testing via the Xbox Insider Hub.
Microsoft Flight Simulator found real success doing exactly the same, particularly after its inclusion in Xbox Game Pass.
