The intended message of the Soviet campaign for world at war was supposed to show the player the brutality of the Soviet army in its vengeful campaign against the Germans. There is a moral mechanic that isn’t present in the American campaign at all where certain decisions affect the ending of the Soviet campaign. Things like executing surrendering Germans is a bad decision and will give you the evil ending for example.

The obvious problem with this is killing Nazis is cool and good so it kinda flys over your head as the player and the message is kinda lost. It also didn’t help that they made Reznov easily one of the most memorable characters in the entire cod franchise.
