4 stars: This game is honestly really fun, but I dislike the fact you have to use in-game currency or real money just to get a decent weapon. Even though you have a good enough Starter weapon, upgraded and stuff, it feels unfair. Also the enemies start getting really annoying when you progress( Even though maybe it's supposed to be that way) and it makes it very struggling. That's why I'm basically here to give it 4 stars.
5 stars: One of the best zombie shooters I've played. It has only a small touch of survival gaming to it and that's what I prefer. The graphics are really good and the controls work very well. Tons of weapons available to buy and upgrade. Spending real money will definitely make the game better but isn't required. If you like killing zombies then this is a must try game!
3 stars: Like to play this game. But reasons for three stars are,1) very expensive in app purchases, 2) very very long waiting period of construction, 3) if you want to play this game without in app purchase, it is very difficult to cope up. I hope they make less pricey in app purchases and lesser waiting construction timing
5 stars: The game was amazing, my little advice here is that getting a gold in this game is very hard, you have to put a specific gold for every mission if you played a mission you get some gold. Secondly, procedure of getting a droon is very hard too and it's hard to open some crest like golden crest unless you use your gold. Thanks
3 stars: Still early...
