If you want a recent review
Since most of these reviews are a year old let me sum up the game for you from someone who is a top player in this game and from the biggest guild. They introduced a gem system which is entirely pay to play and it doesn’t matter how well you build your heroes, as long as someone can cough up money for these gems then they will hit higher damage than you full stop. Also they have characters at SP rarity which, unless you spend over $2000 USD, you will not max for a VERY long time and by then they will have awakened another hero making them useless. Also not to mention the fact that they still have certain prototypes locked behind pay walls and still take upwards of 9 months to release them for people who dont want to spend $100 for one of them. This game is simply not worth playing anymore, it was really fun before SP heroes and prototype gems but now its just a p2w fest as they try squeeze a last remaining but of money out of their fading player base. I recommend you do not download this game, sorry EE
