5 stars: Awesome graphics and excellent gameplay. ZF IV Definitely lives up to its predecessors. If I had to give one negative comment it would be that I'd like to start with an automatic weapon or at the very least a ballistic knife.
4 stars: I am giving 4 stars as I feel there something's which the creator's must give attention to. The upgrade of guns is very slow even if you play for the whole day, you won't get enough supplies to upgrade your weapons. Please look into this matter otherwise the game is very addictive.
4 stars: I like challenges in game but this one is too much, to upgrade anything you'll spend days or weeks compiling the item requirements and I can't make any purchase cos of restrictions in my country. I play to relax and enjoy but it's stressful and the ads after each level is frustrating.
3 stars: I love this game but I really hate the aids, they take me to play stores without I I want, that is really annoying because I have to restart the game, I'd really like to resolve this issue that is why I gave you three stars, keep getting better the game since it is the best.
2 stars: Good game but you have to spend too much money and its expensive , for each area or carrier to go u have to upgrade gun and spend too much money ,i stop playing this game
