The original game at it's best
It's hard not to sympathize with the allies pushing back the Nazis from the snowy banks of Stalingrad, the sandy deserts of Tunisia and the green towns of Normandy. Call of Duty has it's full scope here, whether you're fighting under Stalin, the brits or the US troops on D-day. The new mechanics introduced by the series like proning and shooting from cover really matter here as much as setting a rhythm to progress with your team. Try to go at it on your own and you'll most likely die before you blink. But advance in a strategic way helping the others progress through the german challenges and you'll go through WWII victorious. The world seems more open here than in the game's successors (Modern Warfare and Black Ops) as you can choose the order in which you gain the strategic points of a map and the missions are long. My only regret is that the long last Berlin fight is not present here! And the ending is a little abrupt (SPOILER: Would have been nice to pay through the last rescue mission you get to see on the ending cinematic)
