I have the game so it is zoomed out completely but during this mission I was struggling to complete the mission because despite me having the settings telling me it was had been zoomed out, it was zoomed in. Now with an optional objective where you have to avoid a Retriever Sentinel, it’s really hard to do that when the camera is so far zoomed in you can only see a third of your army.
By the way, Retriever Sentinels are meant to be so tough that it took multiple Human ships to take one down and a Covenant Ship struggled so much that it ended up crashing on The Ark, yet when this thing went up against 3 ODST Squads in Halo Wars 2, I force it to run away
