premise is zombies (iirc there was a mutation at the chem lab and he even gets accused of being infected near the start of the story) - The MC likes to curse and fights a horde of zombies alone as he goes from place to place (and sometimes he meets his other allies there) but overall he's alone and at one point in the story there's a white dog and at another he rides a helicopter for whatever reason. I can't remember much since this is a few years back or if I've finished reading it already but it's an itch I can't stop thinking about. PLEASE HELP
