The game almost compels you to constantly tend to it's need of constant button pushing and checking. The game progresses exponentially more difficult to build as you go bordering on having to use your real money to go forward at a decent rate. Have a friend that has literally spent $3000 on this game. I'm stopping myself at $1200 Kinda like Las Vegas, you have to know when to say when.

I had to dump the whole game, after I finally reached a level 22 base, because I couldn't get the lousy app to start. I dumped the app, hoping to be able to re-load it (hopefully fixing the problem). Now I can't even download the app. I keep getting a lousy error message. So now, everything I've worked for is at great risk. Whoever's responsible, needs to fix the app! Update (12/11/18): This game has become such a joke. It used to be, you could buy shields, for your base, by using in-game gold units. Not any more. You can ONLY use so-called "loyalty points". Meaning, you have to keep playing constantly and taking part in all sorts of different campaigns and such, only to be awarded piddly small amounts of loyalty points. Of course, all of the shields, as well as other highly important items cost exorbitant amounts of loyalty points to purchase. Plus, there are no "micro-transactions", only Mega-transactions. The cheapest package of items you can purchase, using actual money, is $99.99. Every once in a while there might be one for $49.99. The fact is, this used to be a good game, a fun game. Not anymore. It's just a cash-grab, now.

In the 3 years I have played I have probably only put in about $100 total. I am at level 1107 with very high power. It just takes patience and watching for the Easter eggs. I did have this at 4 stars but dropped to 3 because there is no longer a viable way to stay shielded up (you used to be able to use gold in the game). Guess they wanted to mix it up but people spent real money to get game gold. Not a smart move. I not will invest any more money in game packs. Trust of game broken for now...
