Microsoft has announced that Halo Wars has just sold one million copies since it's launch late last month.   We couldn't be happier, after all, we found the two player co-op gameplay in the game to be top notch.  Not only is the game selling well, it's being played a ton with over 200,000 people logging into the game daily.  

Microsoft has also promised to give the game continued support, with newly formed Robot Entertainment taking up the helm on some new content.  There's no word on exactly what the content is, and chances are it won't be co-op, but we can hope right?  

Most likely the next chance we'll have to get some fresh Halo co-op content is in the upcoming Halo 3: ODST game, which is set to release this fall with four player co-op.
