Click to navigate and shoot! Modes: Panic- You have 10 seconds to kill a zombie, once you have killed a zombie the timer resets to 10, but if you shoot a civilian you will loose 2 seconds automatically, and if you hit a bomb that's game-over! Meltdown- You have 60 seconds to rack up as many points as possible! There are no bombs in this mode, but if you hit a civilian you will loose valuable time (and points). Hardcore- The most unforgiving mode, works like panic mode, but there's a catch. If you miss a shot, you loose!
