In the game you just have to shoot only zombies and protect civilians. But then you get money with which you then buy new weapons, or can improve existing ones. The whole is thus quite motivating, even if the aircraft actually revolves only about the same area and you shoot the black zombie silhouettes. Annoying it is when you're almost over the bunker, because then you can not there more "pure shooting" if zombies are here to overrun the bunker. Because you have to be careful, of course, that you do not get there in ambush. On the other hand, it is also impossible to attack waves longer than a few minutes to stand up, because the zombies are coming from several directions simultaneously. In addition, the control system is again controlled very complicated when you want to switch between the weapons. When recognize developers finally on how to hold a tablet in his hand, and how best to achieve things.
All in all quite a nice little game for in between. By Aufrüsterei motivation is maintained.
