This new PC game is set two years before ANH with a certain amount of cross over from Episode 3. Screen shots look superb. It appears to include ground battles set in dessert and greenland areas with attacking AT-AT's and a new Imperial ground based vehicle called "TIE Crawlers" which I've not seen before (cross between a tank and a TIE Fighter). The action also takes place in space with rebel fleets taking on Star Destroyers (think of the game Homeworld). Unsure when the game will be released as it is in the early phases of development.
