Ye, Halo Wars has been in development for years. Its a Real Time Strategy (RTS) Game. The Single player campaign follows the story of the occupants of a UNSC Cruiser that gets involved in a battle against the Covenant over lost Forerunner Relics. The multiplayer allows players to play as the UNSC or the Covenant, its unknown about the Flood but as the story takes place before the first Halo game, its very unlikely. The game plays a lot like Command and Conquer games but there are some unique twists in the gameplay mechanics. With some luck it will stick to its release date and be out this year.
