Finally, I feel like I didn't throw €80 in the trash. The game gives the impression of being well completed, full of new content and addictive. The maps are well made, the weapons have a good feeling, the menu is fresh and most importantly - the game does not have a lot of stupid glitches. Constant FPS and no problems with loading the game is not so obvious, and yet it is possible. After all, Camo Grind is not for a week of work and adding Mastery to Warzone will make players use other weapons rather than Meta. Definitely one of the better versions of Call Of Duty in the last few years.
EDIT: 2 stars. Trash game.
