The trailer doesn't reveal too much. We see that the game is set in the Medieval era. There are two of the civilizations you’ll be able to play as in the game, the Mongols and the English. We see them face in a battle for victory and glory. So, it looks like the game might follow the good old RTS formula of the previous installments but that is yet to be said. In addition, the graphics look very nice.
Age of Empires IV is being developed by Relic Entertainment, and the release date hasn’t been revealed for now.
