The Medal of Honor Allied Assault Website (thanks Frans) has news that the Medal of Honor Allied Assault Breakthrough add-on is gold. Word on availability is the WW2 shooter expansion will be storming store shelves on September 22. Here's a bit on gameplay: "As U.S. Army Sergeant John Baker, players join the battle at Kasserine Pass in North Africa, race to capture Messina in Sicily, and finally repel the German army at the historic battle of Monte Battaglia in the heart of Italy. Armed with a new arsenal of weapons, players will fight alone and with squad mates as they rush to stop the Axis powers. The multiplayer game has been enhanced with the addition of Liberation Mode. In this mode, defeated players must be rescued by surviving teammates to continue the fight. In addition, players can drive tanks, and minesweepers can defuse mines. Players can also choose from American, British, Italian, and German skins in all multiplayer modes."
