The game was fun until round 5. I have not been able to advance since. Gunners sit back and shoot you while waves of smaller enemies move past them towards you and all of your guns focus on what is close. I watch ads for chests the game closes and I don't get the reward. Coins and cards to upgrade your guns do night align with the level difficulty. I feel they definitely want you to pay something to keep going. Help us out devs.
No forced ads, aside from internal ad spam you have to x out of often. Would be 4 star but jorriable interrface. Game will spend the blue gems without double checking. I was trying to exit out of a stupid new menu and where I normally hit to do upgrades had a spend 250 gems on noob trap purchase. I did not want to spend but the pop up registered location of my press before displaying the honorable deal. Now I cant buy the gold mine upgrade game wasted my resources.
awesome game! And yes you can earn 3 stars on every level... it's hard, but can be done but I will say that I do think there could be a few more medkits thrown in there seeing as they are hard to come by but other than that it's a fantastic game. I think the music and sounds are damn good as well same with the graphics and art. And yes the gameplay itself is fun and is quite challenging as well. love it!!!
What would be a very fun game, is completely ruined with their gamebreaking ads. Most of these games has ads, but this game/dev has elected to do ads that last upwards of 3 minutes or more. You can't skip them, and even when the ad has run its course, there is no way to exit the ad or return to the game and mission you're in the middle of. You have to close the game, restart and redo the level, hoping you don't get another one. I have spent money on some games, but not this one, ever.
