Seriously stop wasting money!
First of all the campaign in my opinion is mediocre and surprisingly felt similar to the other campaigns I played. Online is a joke too. All the 12 years olds are back, and campers are too. Additionally, it is also WAY to easy to rank up. I feel that I could go up to MAX prestige in a short time! It still all feels the same like MW3 or even all the way to Call of Duty 4!
Graphics are horrible as well! Did you know that the Call of Duty series used the Quake engine which was from the 90's, then just modify it and put it on store selves? Exactly.
The sound effects are also mediocre and don't sound like guns (Trust me, I did hear real gun shots in real life) it sounds like computer-generalized crap! Why can't they record real gun shots? Looks like they just want a quick buck.
Conclusion, DON'T BUY THIS GAME!
