First of all: Who the first part and the add-on has already fallen, the is no way around Call of Duty 2. In itself, there is not really new innovations. The control is a bit different and getting used to (grenades are now thrown with the G or M key, the mouse wheel can no longer switch between the weapons you.) Innovations that are noticed: The weapon immigrated during shooting slowly upward (recoil) so that a constant attack does nothing. On the small compass of the enemy can be seen by red dots, so you can quickly these locations. There are smoke grenades. The absolute highlight is the graphics. The breath of other soldiers can be seen in the cold, wander in the fog of smoke grenade is madness. The soldiers move and act in my opinion even more realistic. It is a really even aware of really what the soldiers who took part in the war at that time and it is only a game. In reality, it was probably even more brutal. Ok, the game is quite fast but played through by the oppressive atmosphere and the absolutely realistic Done Play the game also like several times. Many write here that it would be an absolute geballere. For my taste, no more and no less than in the old parts. Who as I said the first part like + add-on should buy the game, all others should maybe play the demo before. My conclusion: The best shooter genre.
