The game has potential to be as good as fallout shelter, but one issue I have right now with it is the lag. It needs more optimization.

Once my favorite mobile game, now trash with ads and bundles around every corner

Well this game is not too bad. They tryed to be better then all the other shitty survival mobile games out there and they sure are better in some ways. But they also have the classic problem. So since this is a free game they have to make money somehow so it is obviously made so u buy In-game items instead of farming and not investing any money. Items break really fast you're stamina is empty in matter of seconds and takes way to long to regenerate. The combat overall sucks there is no blocking no dodging no parry or something u can only hit and get hit or you use firearms. And the hit boxes for the melee weapons is just horrible. But they tryed to make a decent game for free and if they just fix those issues it would be a lot better.
