You have 5 days to kill all the zombies before they reach their cave. Becareful, they're imitating the civilians, don't kill the civillian! Before you start to kill, be sure that you can see the difference between the civilians and the zombies (don't be confuse). Remember! just kill the zombies, donâ€™t the civillians, if you kill the civillians 5 times, your mission is over..
