There is nothing better than fresh smell of incoming zombies, gunpowder and logic tasks. All is combined one game which can show some nice number of levels.
You begin as a guy with bazooka but as you go through levels liquidating hordes of undead and letting free new characters with new skills, the game turns to be very various and chaotic. Some levels need your head for planning, thinking and quick deciding. The design is mostly very but very original. Flaming Zambooka 3 would get more points but it has some flaws.
