Honestly there are a lot of times where the game does glitch out or crash on the Xbox One, but it is designed for next gen (series X) so it is completely understandable. I have only played a few missions on the campaign and I must say its pretty good so far. Zombies is amazing, they took the key aspects out of games that I really enjoy and incorporated them on zombies, the health bars of zombies really gives you an idea of the true strength of each individual weapon. The use of armor and the ability to upgrade your weapons more than once is really awesome. I just feel they need 1 or 2 more perks and it will be perfection.
Now onto multiplayer, if you have played a games and anybody is using a burst fire gun its over for you, they need to drop the damage on these to level the playing field. The snipers are under powered and a bit slow but if you know how to use them you can dominate a lobby. Overall I am loving multiplayer but it can cause frustration like any competitive game.
Overall the game is amazing and a need if you havent got it yet.
