No war story can make you feel any sense of salvaged happiness, and this game gets it perfect, with a relentless, unforgiving story split between the US on the Japanese bays and the Russians on the East Front. The US side is used to show special and different strategies used in war, which is shown all throughout the Jungles and castles, while the Russian side shows the dark sides of war in the Russians slaughter ageist the Germans. After is all is said and don e, you are put in Zombies, and i never felt better unlocking Zombies for the first time and being in total shock. Overall a 10/10 game, easily the best COD game ever, even better then the Modern Warfare series in my opinion
