In a world of the infected, there are very few that survive. Your chances of surviving is low at all times, and people who do survive are highly trained and skillful. Those who aren't are more unlucky. Turned into walking monsters, zombies if you will. Leon Kennedy happened to be one of the very few survivor's left. Leon had just got done finishing off a village of the infected, all of them dead and leaving behind goods that Leon could take to give him leisure in the hellish journey.
