Halo Wars is an upcoming real-time strategy video game set in the Halo universe, developed by Ensemble Studios for the Xbox 360 game console. It is the last project to be developed by Ensemble Studios.
Halo Wars is a real-time strategy game built specifically for the Xbox 360 console. Players manage resources and create and maintain buildings and armies to complete objectives. There are two playable factions, the human UNSC and alien Covenant, with their own units, strengths, and special abilities. Players establish their armies by building and expanding bases. There are only a few base locations on each scenario or map, making base fortification and defense a key priority. Destruction of a player's last base results in defeat if a new base is not quickly reestablished. Bases are where units are trained, upgrades are researched, and resources are gathered.
I assume they are releasing it a day ahead of KZ2 to get the jump on Sony's new killer app !
