Well talking about the game plot setting, Halo Wars is set in the same Halo Universe where previous games of the franchise took place. The events of this game begins in the year 2531, 20 years after the events of Halo: Combat Evolved.
You can get free Halo Wars from XBLM. Just vist XBLM over here and get download of Halo Wars free demo from there. The size of the Halo Wars free download is 1GB which I think is not so big. I still remember Tomb Raider Underworld demo was around 2GB in size. So free Halo Wars is just half of the Tomb Raider Underworld demo.
You can check more on Halo Wars free download on the link givenabove but to download demo you need to turn on your 360 because it will get downloaded directly on to it. Simply turn on your Xbox 360, and download Halo Wars free from there.
Well the game has been well received by critics and reviewers.
