Always there with a friendly reminder, Major Nelson sends word that the Historic Battle Map Pack for Halo Wars is now available on Xbox Live Marketplace. The new content includes four new multiplayer maps: Barrens (1v1), Blood River (1v1), Memorial Basin (2v2) and Glacial Ravine (3v3). The DLC also adds four new Achievements worth a total of 100 points. If you need some new space to rock out with your tiny Spartan death squad, the Historic Battle Map Pack will run you 800 ($10). Check out some fresh images of each map in the gallery below.
