It's all about money. no money you are nothing. This game is like a laborer for free play. All upgrades need something to pay for and there's no end. So tired and now im done for it. This is the first tiring game. If you want to get rid of fatigue, I do not recommend this game or you will become more tired and lifeless😂😂😂😂. I'm done for it. UNINSTALL and INSTALL CODM LMFAO 😂😂😂😂😂😂😂😂
