Great game!

I’ve been playing it for 5 days and have unlocked all 4 cities. I still don’t know what all the icons mean ( DPS anyone? ) but I’ve got tons of cash ( hint: get your doghouse auto-working ) and have the most expensive weapons at every level. I paid for a City Pass at the London level and that really bolstered my gold. Also, there’s a setting to double your revenue/damage multiplier for 4 hours if you watch a that. Loving this game but it looks like it could take a while to complete. Crazy mode( icon is an angry red face), which is unlocked by buying a City Pass or once you reach a certain level in each city, helps you get through the levels quicker but I’m still only at level 77 on the 1st city and there’s 200 levels.

Update: Game is actually never-ending. The ability to kill bosses, and make money, is directly proportional to the level you’re able to upgrade your weapons, and as others have mentioned the game starts crashing when you try to upgrade weapons past level 7000 or so. I reached a point in game levels around 1170 and I could no longer kill bosses because I could no longer upgrade a weapon past 7000. On the Sydney level, I had every weapon at at least 3 stars, and the top 8 weapons fully transformed and leveled up, but could only inflict about 50% damage before time ran out to kill the boss. Money wise, I was up to CR. I deleted the game because I couldn’t advance.

Great fun, with Optional Monetization (broke game)

Found this game through an ad, and liked the look of it, so I downloaded it, and booted up. I find the gameplay actually really enjoyable! No forced ads, which is a big plus. You also don’t have to spend a single dime on the game to do well, just watch the optional ads to get some pretty generous boosts. I “completed” the game in just a few days, however, due to what I would call an exploit that I found. Once you upgrade any turret just once, you can watch an ad to increase its level by so many without paying any in game currency. The “problem” here is that every time you do, the levels you get per ad increase. This means that a 2 star turret gets 10 levels, with an additional 2 per ad watched. Since dogs scale with the power of your turrets, and the first dog each area can be auto’d for only 10 gold to give a cash drop every five seconds, it creates an exponential loop, giving you more and more money each ad, quickly surpassing the cost of the last dog. This is where it gets broken; you can use this metric boatload of money to reset the first area hundreds of times, adding on another exponential increase. I got to the CK’s then the game crashed around a 34,000x multiplier. Did all this in just a few hours of absent mindedly clicking the ad button, and now the game crashes when I click special weapons XD.

Great, free entertainment breaking this game!

Love it but hate it

I’m a type of person that love these defensive games. None of those building territory games that take forever. I like constant needing to upgrade your weapons to beat the next wave of enemies, in this case, zombies.
I have to say, this game is good, but it’s not great. I don’t like how they throw you in the game without any tutorial to how the game works or functions, then the wave starts coming in without warning. You have to learn everything yourself. Then they expect you slice with your finger to damage them, which is ok. I like the fact that they want to you to interact with the game, but it’s not fun when there are ads that pop up every so often. I’ve had the window pop up to pay for the item and I had to cancel it.
Then, it’s expected that for every game they want to pay for the increased upgrade or perks, but it’s ridiculous how persistent they are to want you to pay for things.
Guess how long I played this game to get all these problems and right this grieving review? 20 mins. Lot to learn.
