Edit: dont spend any money! Not until they fix the glitches. You could end up getting random garbage. I spent a week and some money, working toward a hero as a reward. And the event sent a different hero. NOT the one in event description. From 5 to 2 stars for this. Unacceptable! they did a great job of capturing that game. As well as adding in some multiplayer features that are fun also. Like arena battles. But also guild co-op content. You really dont need to pay to enjoy this game at all.
