Fun time killer that you can play with no internet, however I have three headgears that I haven't unlocked, three tops/shirts I haven't unlocked and three bottoms/pants I haven't unlocked but I cant unlock them. Whenever I complete a level I don't get closer to unlocking a cosmetic, it just skips that part completely.

Love this game. I'm almost on level 2000 at casual playing time, so I've been playing for some time. Ads between each level, but it doesn't bother me. They don't really last that long. When needed, you can watch an ad to gain 3 lives or purchase them. You sometimes get to try a bonus weapon, then an option to purchase it, or there are the regular weapons that you can purchase with the coins you earn on each level. The costumes and helicopters you earn are pretty neat, too.

Great way to pass time. It's fun and easy to play. My only complaint is not being able to see weapon stats before purchasing. I hate saving for an expensive weapon only to find what I already had was better. Game does not link to any account. if you change phones or factory reset all your progress is lost and you have to restart from level one.
