Une nouvelle expansion pour Medal of Honor: Allied Assault serait en cours de développement, avec pour objectif de retracer l'histoire de la campagne nord Afrique/Sicile. Ce nouveau volet se nommera donc Medal of Honor: Breakthrough.

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, artillery spotters can call in artillery strikes, and minesweepers can defuse mines. Players can also choose from American, British, Italian, and German skins in all multiplayer modes.
