No idea what town I was in, but I saw a survivor run across the street from where I was lying prone and start caving in windows with a hatchet. The only potentially lethal item I'd looted at this point was a hand grenade. As I stood up to lob the frag at him, he sprints across the street towards me. I'm not sure if he managed to connect with his hatchet, or if the grenade blast caught both of us, but when I woke up after a minute of unconciousness and bandaged myself up, my murder count was at 1. A bit of a dick move, but what else am I to do with a hand grenade.
