Kinda fun...for about an hour. After you finish all the levels they just reuse the very same things you've just completed. The only things that might give you a different experience in the levels are the guns, but most of them are just reskins of the very same gun. And the ads. Where do I even begin with the ads? There are so. many. ADS. It has a lot of ads for a mobile game, and that's saying a lot. Overall, a good time waster, but as soon as you finish all the levels it gets boring real quick
