It’s not that it’s a bad game, I like it. However the reason that I am disappointed in it is that it’s exactly the same as MW2. It has new maps but the nearly the same weapons, same campaign storyline, about the same kill streaks, and many more similarities. Spec-ops missions are are the same and the only fun unique thing is survival. At best, I’d call it Call of Duty: Modern Warfare 2.5.
I will still play it, as I loved MW2, however if you are skeptical of buying it and already have MW2 I’d recommend saving your money for something else. MW2 has a great and still active multiplayer. The only reason why I’d recommend someone to buy MW3 is for its survival mode. The survival mode on MW3 is amazing, addicting, and so much more. Survival mode itself, although, is not worth the $60 you pay for the game so unless you really want to play this new mode, just stick to MW2. Happy gaming.
