Halo 3: Recon might still technically be an expansion, but the looming questions is of the game price and distribution type. Here’s what Microsoft had to say “This new chapter in the Halo saga lets you experience events leading up to the epic story told in Halo 3 through the eyes of a new hero in the Halo universe,” this statement was taken from their website and it goes on to say that, “The stand-alone expansion, set to release in fall 2009, extends the award-winning Halo 3 experience with hours of new campaign excursions and multiplayer gameplay.” If you missed it they said that the game was a “stand-alone expansion”, which means that it will be going on sale by it’s self. Since this is basically a new game it can go for the price of $60 like any other retail game on the market. Halo 3: Recon will be making it’s release in fall of next year.
