In a post written Dan Ayoub, Studio Head of Strategy Games at 343 Industries he reveals that Halo Wars 2 is getting a second beta, with lots of changes.

Hey Guys,

I first wanted to take a moment to thank everyone who participated in the Halo Wars 2 Multiplayer Beta this past June. As a reminder, this was more a technical preview of where we are in development, or as I like to refer to it, a true development beta.  This not only enabled us to test our backend and tuning, but also to put the game in the hands of players early enough that we could respond to feedback.

He goes on to explain the changes to the Controls, Bases, Resources and Power and much more. It’s also revealed that the beta will be available on Windows 10 and the Xbox One.
