Pretty shameful to see the repeated copy and pasted 5 star reviews for this game out there. I personally don't own the game, but I've always been a major skeptic when something is rated at 5 stars, so I actually took the time to scroll through and read through a lot of them. In the first 5 minutes, I found 3 copy and pasted reviews that were obviously written (copied, rather) by employees to boost this game's review base. Shameful. The one star reviews that go really far into detail are written by people who very obviously care enough to actually unlock most of the unlockable content to write these reviews, and this company has basically hired employees to denounce them into oblivion. EVEN then, they failed. Game still wound up with a 2 star review. I'd definitely say it's a safe bet to never purchase this game, let alone another Call of Duty game ever again. A company that does that is just specifically looking to profit.
NOT TO MENTION: Looking at the map list, there are SO MANY maps brought over from the last 2 CoD's. They've basically just copy and pasted their own game and are charging full price for it. Not worth it. A simple youtube video or google search can show you all the maps in the game and professionals are BY FAR disappointed with this one.
