Fun game concept. Quickly becomes impossible to get further, like within 2 days of playing on occasion. Inundated with ads that give you only a small benefit at best to watch. There are paywalls set up in the game. Want the 4th weapon slot, pay ~$5. Want to upgrade weapon to legendary, pay ~$2. Would've preferred this been included for free through play pass or just charged $5 for the entirety of the game since the concept is simple.
