I have played all Call of duty series launched before this. I can say that developers pour some level of enthusiasm when programming this game. They hired good professionals to take care of every aspects of the game.
In the case of this installment, I could say that some air of SW Rogue one is in it. Specially in the robot where tries to be funny and charismatic in order to make sure to get emotionally link to it.
The story is very good, I enjoyed it. Side missions become most place because they are enjoyable as main missions. The length and difficulty of the game are perfectly balance. Never get bored, frustrated or unsatisfied.
It has two great additions: Zombies and Multiplayer. Both are great.
Highly recommended, specially now that can be found at a very low price.
