The campaign in cold war reintroduced the feature in bo2 where you can choose certain things and it will affect the storyline, for example in one mission you save park or the black guy before cuban forces arrive and it's too late, it's just like in bo2 where you can kill harper or have farid shot by menendez, the story is also great, a badass team of people trying to find the most dangerous spy to ever exist, perseus, btw irl perseus was an actual spy, the game uses real footage, which is just awesome, it shows that the modern warfare trilogy and black ops trilogy are in the same universe, and you homophobic fucks can get mad about the fact you can make your character non binary while making who bell is.
