Xbox One - New Update

New troops unlock each week - new kingdoms unlock on that cadence as well. Since we didn’t know exactly when this week the update would go live, none of the new troop events begin until the start of next week. The weekly events will let you know what new kingdoms / troops are available each week.

To summarize, no new troops/kingdoms were added to the update, and will instead continue to be added on a weekly basis as per normal.
