The future is not bright as zombies are everywhere you go. You need to clear them out or they would feast upon the villagers, not to mention you. You are the villages last hope as you are good with a gun. The idea here is to kill all the zombies in an area. You can move to the new location once you exterminated the zombies in an area. You need to reload your gun once you run out. It would take some time before you can reload your gun, so try to stay out of the zombies way or you would regret it.
