★☆☆☆☆

this game is crooked, I had lost battles when I'm 3 times more powerful than them, and is only because I get so much more enemies at the same time than them. for example I have 500 of power, 5000 of hp, and 80 cards with different abilities, and I loose with someone that has half of it. I spend $50 one time and I could only pass one level with that amount of money. never playing this game again and I'm going to use my YouTube channel to talk about you. my channel is about games. now is your turn

★★★☆☆

Fun game and easy to learn, but the RNG of the cards is maddening. If you could customize cards you like and ones to not use, that'd be amazing. Otherwise you get stuck on levels like Normal 15 which seems impossible unless you get the perfect cards AND targeting RNG. Between that and the gear system being very hard to swap from mission to mission, it needs some fixes before it's worth a higher star rating in my opinion. Otherwise this is just a grind fest.

Fun for a while, I spent money to remove ads. Guild system is terrible, almost impossible to join existing guilds, cost lots of in game currency to start your own, which was an odd choice. The thing that made me mad enough to delete the game and leave a review was after spending an hour on a challenge level, finally have all the right turrets and most of the cards I want for them, and before I can finish it the daily reset forces the level to quit instead of letting you finish like other games.

★★☆☆☆

Prepare to pay and beat your head on many walls. Events? Forget them. You have to buy your way through them to get anywhere. Progression is heavily RNG. Be ready to spend up to hours on the same boss mission until you just barely make it from just the right set of cards. Don't bother with anything with leaderboards. P2Wers buy their way to the top. Severely one sided encounters. At times there are around 200 enemies on screen and weapons have VERY janky targeting.
