About two months ago, a experiment tissues escaped, becoming zombie virus. Since that time, everyone is trying to survive - some in groups, some alone. You were this second type. "You don't have any group, do you?" A blond, tall man asked, he was in group with 3 other humans - some gril in googles, another a bit taller than this one man, and another guy, this time short and with black hairs. You had problems with a group of zombie and they saved you.
