Zombies are not powerful enough, you know there are how many military bases on this island or whatever & the military got taken out with all their armour, aircraft, infantry & whatnot. Yet when we find a gun we can take out how many of them by ourselves. There is an abundance of food & arms & ammo so people really have no environmental way to die. And also if you do get a gun the zombies can't even hear it from that far away, you can just shoot from the bushes out of town at people & the zombies will just stand there. For how large the island is there should be WAY more zombies or there should be at least random hordes that consist of 100s of zombies roaming around. Also to make the zombies harder to kill make it headshot only.
