Here is a video:
Halo Wars is a real-time action strategy game for the Xbox 360 that allows the player to control large armies and to shrewdly direct them in realistic warfare. Set early in the iconic war between the Covenant and UNSC – made famous by the Halo FPS games – Halo Wars provides a new angle on the war while bringing new heroes to the battle.
The images below are renders of the units or buildings in-game. Mouse-over each image to see the original concept art. In the weeks and months ahead we will be updating the features page with more information and imagery.
