This game is too much stress and resource for stuff you need, some things need 10 items to 15 for one item and the worst is you need to buy most things with gold, from my experience devs want to take my money, sorry this game i deleted for second time for good, all about money, then you switch to zombie, to change back pay 50gb,ensane,why not for zombie change too, the higher you go lvl the more difficult it is to get resources for stuff you unlock, devs are crooks, i rather play my genshin.
