I thought the campaign was tons of fun. Theres a neat bit you can to do with intelligence gathered and an entire mission dedicated to sneaking around in the KGB headquarters. Theres also a few choices you make that have minor effects on the story telling. Overall I give it a 8/10 but could have more content. Zombies are also a ton of fun, return to the old style of train and mow them down vs Easter egg to win.
