Coming exclusively to the Xbox 360, Halo Wars is the latest game in Microsoft Game Studios' premier gaming series. It’s being developed by Ensemble Studios, the same company that created the ground-breaking and massively popular Age of Empires series. The real-time strategy game will feature human and Covenant forces, and is set 20 years before the original Halo game. There’s no release date set yet, but expect it to be just as popular as Halo 3, which sold $300 million worth of copies in its first calendar week.
