Great game loving it so far. However it is a bit expensive to buy things. A good example is has like a battle pass first tier free second $5.00 and 3rd $15. I'm thinking if you pay the $15 tier you also get the second $5 teir. Unfortunately you don't you have to also pay for the second teir as well. Another example they have a 3rs teir $50 and the second teir $20. You have to pay for both not gonna spend $70. That have alot of that. It is a very grindy game but that's a free to play game.

It's a decent game till you hit level 10, then the scaling creates an impasse that takes weeks of grinding the modules just to pass, or pay for it, seems like a massive cash grab game. 10 a month for no ad rewards, and bonuses to actually progress, or 50$ for a life time of that. I mean..... This dev leaves a bad taste in the mouth all around. Shame on yall.

Good gameplay, but if you are f2p, it is like an ad farm, you will need to watch long ads to do even some of the most basic things. There is a lifetime battle pass for 50 bucks that gets rid of all the ads. They also locked 2x speed in the lifetime pass, speeding up gameplay is not free, lol. That aside, while the gameplay is good and addicting, it is a long grind. Cash shop stuff in the game can really help speed up progression, but it's kinda expensive.
