Fortress Italy is the latest in the Combat Mission series by Battlefront.com, and is the first to feature their new CMx2 engine Version 2.0.
Fortress Italy charts the Allies attempts to knock Italy out of WWII. Launch content focuses explicitly on Sicily, and the game will feature troops that fought in that particular theatre of war (including Italian Bersaglieri, American Rangers and the German Herman Göring Division)
It's a stand-alone title, and doesn't require any of the previous games in the series to run.
Battlefront.com included a load of beta screens with their announcement, and here they are:
