Massive dissapointment and a waste of money. The game is clearly unfinished with its lack of content online (incl. Maps, Game modes). The campaign is decent, if you are not having issues like Blue Screen; Save deletion; System shut down or disconnecting from your network, even if playing offline.
Zombies is also okay although, theres major bugs when connecting a secondary player and the split screen is God awful. You have a border around screen and the in-game HUD is decreased in size and packed into a small box. This makes it extremely hard to see or play, even with a large tv.
I have heard a lot more complaints from Series S and X users about graphics, gameplay and hardware issues when playing Cold War.
I really hope they fix these bugs during December or they will have a lot more complaints from others that are waiting to Xmas to play this "cash grab" of a game.
Buy Valhalla or Watch Dogs Legion, that way you're paying for a finished product.
