this is not a hack. i got this same thing in two towers and i didnt even have hacks on. i alt tabbed out to check some torrents and i came back and this same thing happened. First, i had 600 hp and it showed as zombie in corner even though i was human. then zombies started attacking me and all i did was knife. ended up with 200 deaths tho. headsup you really havent played in a while have you?
