I'm tired of ads showing games that are not even remotely like the videos they advertise, so now I write reviews every time I see this, detracting one star from the rating I would otherwise give, and explain a bit about what the game is actually like. If you're going to show ads with gameplay, show gameplay that is actually in the game, and which makes up most of the game, and is available within the first day or two of playing, at least.
In the case of this one, all the ads I've seen show impossible situations that noone could ever win. This is another really stupid thing about these ads. It really gets old. *None* of these situations are actually in the game, at least not for the first month or so. I've been playing it about a month, and I have yet to see even one thing that is anywhere in *any* of the ads for the game. What it actually is, it's another post-apocalyptic civilization building game in a zombie infested world. There is a traditional tower defense game element for you to play, this gives you rewards for the rest of game. The storyline is not great, but it's not horrible, either.
The game does really try to push you to purchase stuff, and you will have trouble without purchasing anything.
All in all, if you like civilization building games, *and* you like tower defense type games, you *might* like this one, otherwise, you won't like it.
