Personally, I love the sound effects and graphics. I think the campaign is pretty interesting and although it's a little short, it makes up in story. People say this is "propaganda" but I think it's just fine. Its great!! It has a great and more realistic multiplayer and its overall a very fun game!
UPDATE!!
The spec ops is fixed and I love it! Warzone is great and I'm sorry for not mentioning it in the first review! Wow, just wow. Best COD in years. This game gets way too much hate and is too underrated. Great game with some great maps. They edited the footsteps and the weapon customization is just spectacular. Like I said, this game doesn't get enough credit! The modes are great and this game has some of the best maps in COD history in my opinion. Speaking of maps, I loved the idea that they brought back Hardhat. But now I'm just going on a rave. To put it simply, thank you Infinity Ward and Activision for this intriguing, amazing, stunning and just downright BEAUTIFUL FPS. This was worth it.
