I know a lot of people don't give 2 damns about the singleplayer but for those who do here's my short review.
Just finished it on XB1 and I have to say it was FANTASTIC. Everything was done well, the story, visuals, audio and cinematics. In some of the previous CoDs the story was meh but they developed this one really well. They also kept the button mashing cinematics to a minimal and when they did come about it was epic. The exo movements and abilities were incorporated really well in the singleplayer.
Highly recommended.
