With the Generals Handbook about to make an appearance next week, Games Workshop is letting out a little bit of information regarding just what this will mean. Battleline Units are the troop choices of the Age of Sigmar, and the entry above from the Age of Sigmar Facebook page gives us that and a little bit more.
Also a Season of War starts in July.....
