According to a post on the Age of Empires II: HD development blog, the now 16-year-old game will be getting yet another new expansion later this year. In his post, community manager Kieffer Bryant said that the expansion will include "new civilizations, campaigns, game modes, units, and more," but didn't offer any specifics beyond teasing an image of one of the new units shown above.

This will be a follow-up to The Forgotten expansion released in 2013. It added two new game modes called Treaty and Capture the Relic, a spectator mode, larger map sizes, five new civilizations, and four new campaigns.

Bryant also announced several changes for the game's latest patch that would be hitting Age of Empires II HD this week. These include better optimization when large numbers of units are on screen and an improved system for managing multiplayer lobbies.
