Campaign is average. OCS missions are a decent concept but are clearly here due to the rushed nature of the game. Story itself feels like the first half of a full game that was made into one game.
If the matchmaking system wasn't as strict as it was, the multiplayer could be so much better. At times it feels like a WWE match: Its all scripted and the ending is predetermined. Aside from that the weapons and overall feel of the game are much better than MWII. The remastered MW2 maps generally play the same, which exemplifies the issues with some of them due to the faster nature of the game. Ground War needs attention as its the best place to avoid the matchmaking algorithm but due to lack of maps and the EMP extended play sessions can become tiring
Zombies surprised me in the sense that I expected this to be a complete disaster but instead was overall slightly above average. Server instability continues to be a problem for the mode to this day and due to the extraction mechanics of the mode can become a big pain point. Post launch support has been odd since they continue to try and evolve the endgame but most of the playerbase has not even finished act 3. More midgame content needs to be added (contracts, ways to lower cooldown timers, etc.)

This game could've been an 4 or even 4.5 if it had more time but overall enjoyed my time more than I hated it
