The game is made entertaining and quite good in itself, but the gaming experience is ruined by the massive in-app purchases, as it in some maps may not waive it. I sat on a map for days and did not manage to hold out until the end. Obviously, the game is not designed to win alone with the selection of available units. Instead you have to use supportive means, however, that cost "Stars". Stars you earn just by completing a Map. But if one has no more stars, the game is unplayable and you will get frustrated quickly. Now all that remains is the possibility to buy star. But who has desire, to spend up to € 50 for a measly app (especially nan has paid anyway for the app). Apart from this, there are still something to complain about the gameplay itself: You can not adjust, which aim to combat units. Always tackle the foremost, which means that the antitank senseless shooting at infantry, while right next to their tanks roll past. All in all, would the app deserves 4 stars. But there is the compulsion for in-app purchases, even 1 star is too much.
