5 stars: Really solid game overall. Ads aren't forced and realistically improve your experience. Game is challenging, but not so difficult that you don't keep coming back. Replay value system rewards mission objectives well. Would love to see a survival mode or other mini-games within, daily challenges, etc. Overall very well done.
4 stars: early in the game but, so far it's pretty legit. the graphics as well as the feel and gameplay is pretty smooth. my only gripe as of now would be that the rewards for when you complete a mission is pretty weak to damn near non existent. on top of that there's barely any ads to save up for upgrades. so what I deduse from that is it's essentially pay to play and that's too bad because its a pretty good game.
4 stars: A great game UNTIL it gets a bump in difficulty with having to level up the weapons, which is fine but it's a big jump so you are having to play the same level for a long time UNLESS you pay. 4 stars because it is a good game, just annoying with where I've got to making it very repetitive
2 stars: This is a fun concept for a game but unfortunately it's pay 2 win/pay to play trash. Your ammo is severely limited and if you manage to pass a level the rewards are minuscule in regards to what you need to level your weapons up. Completed missions can be replayed but won't net you any in game currency. Upgrade card slots require absurd amounts of gold. This is just a very greedy cash grab that I cannot support. Or afford to...
