We dunno when exactly the outbreak started. But Ryan mentioned that "there's more and more since last night" when he talks about the zombies in the beginning of the game. So, it probably happened the day before or something. Idk. & that's true, and doesn't the Fortune City outbreak happen at night O.O more beserk-ness!
