I bought it when it was on Summer sales.At first i was hesitating whether to buy it or not.So i made the movement and i bought it and i have to say that i have never feel regretted for my choice.It's a really good game,with realistic sounds and recoils,with good maps and an unexpected good community in my opinion.It is like a compination of CS GO and Arma 2........

I purchased the game at about March 2015.It's a very fun-to-play game with realistic gun recoils.It requires true skill to play this game and rank up.Nice-built maps to play on,especially all-time classics Mirage,Dust 2,Overpass and Cache.It was a very good game until it became free to play.Many hackers and trolers downloaded the game,achieved prime status with minimal effort.Now the game is full with hackers and low skill players and the unfair-matchmaking has really been the main disadvantage of this game.
Another all-time classic problem is that it's almost impossible to control game bots during the game.It's very frustrating in competitive mode when a teammate leaves the match.
So,pros are:
+Nice-built maps
+Realistic gun recoils
+Good communication options(mic,etc.)
+Fast paced gameplay
Cons are:
-Poor community,many hackers,trolers and griefers
-Poor report systerm.This is a more generic Valve's problem.
-Impossible to control bots,very frustrating especially in competitive mode
-Poor servers,high ping and if not so,too many packet loss results in bullets not going where you aiming to
In conclusion,it's a very interesting and fun-to-play game but you have to play with a full team premade to enjoy the experience.
