Age of Empires might not be one of Microsoft's biggest series, but fans have been enjoying the history-filled real-time strategy and massive battles for a very long time. Age of Empires 4, developed by Relic Entertainment, will we the long-awaited next game, and a preview event has given us some new information on playable civilizations and improvements--including powerful war elephants.

The Delhi Sultanate will be a playable civilization in Age of Empires 4, and they have access to the massive War Elephant unit, similar to the second game, for causing massive chaos during attacks on fortresses. Sending a few of those through a group of enemy soldiers should be enough to disrupt their lines and let you push deeper into an area.

One of four campaigns available in the game, the Norman campaign begins at the Battle of Hastings in England and follows Duke William and descendants Robert, William II, and Henry I as they fight for control of the nation. This means it will take place over about 100 years, but shouldn't be confused with the Hundred Years' War that followed a few centuries later.
