Campaign is fun, spent around 8 hours on it. All the missions are fun and provide a unique gameplay element keeping it fresh.
Co-op is very hard even after the updates. If you and your friends are in the mood for a challenge try it out. If not then just avoid.
War zone is great. Hard if you’re playing solo. But it’s always fun with friends. Just keep in mind people cheat a lot. Hopefully they will fix that soon.
Last is multiplayer. Not as good as previous cods but there’s still some decent moments. Maps are on the bad side. Gunplay is fun when you’re not getting shot from behind. Customization is cool and something new. Probably the best part of multiplayer is the streaks. VTOL, advanced UAV, chopper gunner, gunship. Good luck earning them, but if you do they are rewarding. Matchmaking is by far the worst thing.
Overall, decent game with a lot of flaws.
