Be careful, a small part of the zombies have been severely impacted, giving them special characteristics, which can turn your simple mission into a terrible hell. Quickly take your basic equipment and kill all the zombies to make the area peaceful again. Once you have achieved your goal, return to the base and upgrade your equipment for your next missions.
