Ok. I have played for about 30 hours now and love the game, however I am having problems with my blood level. I like the idea of not starting with a gun. But the combination of having to find matches, ax, and a hunting knife, and water seems to get me killed. I cant find them all during one life, and never found matches and only once found a knife. Do I just head to super markets for food or best to hunt for food?

Ok. I knew I was doing something wrong...never made it to the store. Just always thought I would stock up at deer stands and the low value towns. Will try again! Thanks for the responses. Happy zombie hunting!
