This game is the worst thing I have ever seen. Game breaking bugs, terrible aiming controls and pay-to-win aspects that puts FIFA's pack buying system to shame. I have played CrossFire X since its release and not one of the countless bugs that severely break the game have been fixed. Not only that, but the developers show no signs of trying to fix these glitches. One of these glitches is the vaulting action. When you try to either climb through a window or vault over a stair case, most of the time you will stagger and fail to climb, sending you back to the bottom and wasting 5 seconds in doing so. This game is not worth playing and is without a doubt a terrible game.
Just to improve my argument, I tried loading into a game, got kicked because the game was full, then tried loading into another match and joined in 0-3 losing. This game has terrible loading times and can not put you in a game that has not started. You either join late or not at all. And when you do join, you are stuck with indescribable lag and, sometimes, a continuous loading screen that carries on throughout the round you joined in.
Don't play this game. If you want to play a game with Search & Destroy, play either CS:GO or Call Of Duty. Just don't bother playing this game until the developers either fix the horrible bugs, clear the ridiculous pay-to-win aspect, or sort out the terrible aiming system.
