In order not to come across cheating PC players you have to turn off crossplay, war zone is pointless otherwise.
Campaign is quite good, multiplayer alright (again make sure crossplay is turned off).
1 star is owed to the fact that it takes up sooooooooo much hard drive space it's stupid, and every time you go to play it you can't get online as you need to download an update, after a few hours it's done and you think "great", but no, now you need to do more updates. So instead of a quick game online your ps4 is sat, for HOURS, updating.
And leaving your PS4 in rest mode to allow automatic game updates? Yeah that doesn't work either.
