I would just like to make something clear,

-The reason why the recent reviews are now at a "mixed" percentage is due to the free weekend where new players have joined and experienced a small amount of the game.
-Anyone who has bought the game and put in atleast 30+hours will know that this is a game that reinforces classical tactical gaming and ingame teamwork.

-if this is what you are looking for then buy it right now! bearing in mind this is the best tactical warfare game that I have seen in a long while I would be amazed to see something top the teamwork aspect of this game.
-WARNING! if you are a scrub who plays COD stay away! this is not the DLC of COD Advanced Warfare!

Overall:
good, friendly community
helpful teammates
good classic tactical gaming
great mechanics that induce teamwork
And this is just the beginning!
(graphics may not be amazing but bare in mind it's still the Alpha stage it's actually fairl good)
XD ENJOY!
