As other players mentioned, too many adds. But that's fine we play for free (if you do not purchase anything). So, they make money from adds. But what the heck is wrong with this game. I purchased a tier two sniper for over 39K golds, but then the game asks me to buy it again. So, you play and buy a new rifle, this game will reset it and it will appear that you didn't buy it. The only problem is that you get to lose that golds too. So, you lose the rifle and you lose the coins.
