Historical inaccuracies are terrible in terms of armament. When creating a game and referring to historical battles, it should explicitly respect history. Also, in terms of realism, I would say no, it is mediocre in terms of sound. The scopes and supposed upgrades to the weapons are completely irrelevant, as they have mixed weapons together, creating a jumble of weapons. Many weapons that appear on the maps have not even been mentioned as existing in the battlefields mentioned in the game. They simply threw them in, knowing that most people would not pay attention to these details. As for the multiplayer, it's a disaster. Just from the abuse that the weapons have suffered, the game ends there. I would choose Call of Duty 2 a hundred times over this. As this series progresses, it gets worse.

Very good. Far better game with 2PP compared to ww2.
The campaign is very enjoyable, obviously the story is fictional and has no relation to reality but the gameplay was good.
The multiplayer is also nice and fast. It stands on its own as a game and it is not mandatory to get it for the warzone.
