Unlike the other zombie games, in this game, you are not only using your gun to shoot em but also using traps to trap them. As your gun is not always powerful enough, you have several tools which you can use to assist killing the zombies. You can seal the zombie gateway by the fences, and set up traps on the path they will be passing, and stand beside and see how the zombies be killed by the whole trap you set.
Yeah! That's all about the game! Zombies! Use your imagination to trap the zombies! Time to rock, my sherif!
