One of the bigger announcements to start X06 in Barcelona was the confirmation that a Halo RTS was in the works, from one of the big names in the RTS genre, Ensemble Studios. Halo Wars will be appearing on the Xbox 360, and the official web site for the game has launched. The site offers backgrounds and a high definition download of the trailer that was shown at X06. The FAQ for the game indicates that this will be a prequel of sorts, with the battles taking place before the first Halo game as the war between the USNC and the Covenant escalates.
