Microsoft has released the latest ‘booster pack’ of content for Age of Empires Online in the form of a new Skirmish Mode. This mode allows players to join together and combat four computer controlled AI enemies, each of which can utilize a variety of different playstyles.

The new mode also grants access to all units currently available in the game regardless of the player’s level, which is useful if you haven’t advanced particularly far and are interested in a preview of what to expect.

You can view the video for the Skirmish Hall Booster Pack below, and head over to the official website for further details.
