MW23 campaign feels like a sloppy unfinished mess with like 90% of the missions be the dreaded "Open Combat Missions". I would leave it at and give the game one star, if it wasn't for the multiplayer. The multiplayer brings back old movement and old maps, it also fixes so many things I hated about MW22. I only played for about 2 days and was already level 25. Leveling feels easier, but still takes work. As for zombies, I haven't played it enough to have a true review on it.
