Pay to Pay in every way. If you dont have 100s of $$$ to get the things you need DONT play this game. And dont get me starfed about the mini game that are suppose to get u the upgrades u need all behind MORE $$$ skins and weapons ALL $$$. Devs want to know WHY peps wont play its because your WHOLE game is behind a GREEDY pay wall and it sucks. At least raise the ## on the drop rate 1% is crazy work. Fun game at 1st to bad EVERYTHING cost.DONT WASTE YOUR ⏲️

Game forces you to get other turrets because the devs can't add in more depth to play as you want. Aka super level the basic turret not possible. Simple thing that either determines if you are a 'Copy and Reskin' of this game genre. If the generic is what your looking for then this isn't that bad actually. But there are better versions

The packages sold in the game are too ridiculous! $14.98 for ads removal and useless items 30 days and $48.99 for permanent ads removal and useless items prices are too expensive! And more expensive packages in the game, Heavy p2w game. Long and annoying ads are all tricks in games to trick players into watching ads with rubbish rewards, there are 20 fixed ads every day, and I spend more time watching games than playing them, nothing special with the game but full of ads, trash game developer.
