Brothers in Arms: Earned in Blood

Continues the Brothers In Arms saga as newly promoted Sergeant Joe "Red" Hartsock (Hartsock was the Corporal of Baker's Fire Team), who was part of the historic Normandy invasion in the previous game. Earned in Blood includes several new multiplayer missions, weapons and vehicles, plus a new co-op skirmish mode. The AI of enemies has also been improved considerably in this game, while level designs are more open-ended than the original. (wikipedia)
