5 stars: I've been playing this game for a couple weeks now and as others have mentioned it is a building type of game with zombie killing fun. I'm glad this game lets you progress at an acceptable rate without having to buy packs daily. If you get in a large alliance with active players you can grow much more quickly. I'll keep playing as long as the game lets me keep progressing.
5 stars: Excellent strategy game with a lot of help from the developers. So it is perfectly balanced. Keeps you hooked due to the fast progression and varied challenges. EXCELLENT....
4 stars: Overwhelming. A ton of pressure to spend real money (I get that the point of this is for business, but make it appealing). Takes a really long time to upgrade your city. Lack of tutorials. 3 stars for the cool graphics....edit: 4 stars because you guys replied.
2 stars: Way way too complex, so so many upgrades required. A lot of the ads that this game pushes have nothing to do with the main game. I've heard in later stages it does appear but it's more a resource management game. Ended up playing an hour and deleting it. Ultimately a time waster and pay to win mechanics.
2 stars: I do enjoy playing however to upgrade anything as you progress takes wayyy too long. I refuse to pay real cash so early in game play. where the battles are concerned, to level up your fire power takes wayy too long as well. I have been stuck for over 3 days trying multiple strategies and still cant get past wave 5. Aga...
