Most of those who aren’t dead have turned into bloodthirsty zombies. Few survivors, however, are immune to the disease.
These people don’t have it easy, since they need to fight for their lives all day long. Your hero is one of those people and you’ll need to help him survive in this inhospitable land.
To survive, try to look for empty buildings and water sources. Avoid zombies that can attack you at any moment.
Try to move slowly in a car or a motorbike, since you can cover more ground this way and it won’t be as dangerous as going on foot.
