The Major's updated to reveal that the Halo Wars Historical Battle Map Pack is now available for download.
Expand your Halo Wars experience with the Historical Battle Map Pack Add-on. These four new maps highlight key turning points in the epic war between the UNSC and Covenant forces. The maps include: Blood River – battle a single opponent over a treacherous natural chokepoint; Barrens – engage your enemy in the midst of the Flood; Memorial Basin – two vs. two team play in one of the bloodiest battles in Halo history; and Glacial Ravine -- three vs. three action as you fight to control a narrow corridor flanked by energy walls.
It's 800 MS Points. Go get it.
Update: CVG's also got some screenshots. Head on over there and check them out.
