Black Ops Cold War is set during the early 1980s of the Cold War. Its campaign follows CIA officer Russell Adler as he pursues an alleged Soviet spy, Perseus, whose stated goal is to subvert the United States and tilt the balance of power toward the Soviet Union. Multiplayer will have new game modes, more extensive customization, and new map dynamics and elements.
The single-player campaign of Call of Duty: Black Ops Cold War is definitely worth playing. It only takes a few hours to play through the entire storyline including side missions: Operation Red Circus and Operation Chaos. All these main and side storylines are the place where the game shines. The characters have depth, excitement is built up and a grand finale awaits you. Where in some areas small steps have been taken back in terms of realism and artificial intelligence, I am glad that they have made progress in terms of offering variation in playing style and possible choices. I had fun with the single-player campaign, and I recommend it to everyone.
