So I was playing and for the first time had my Wii U hooked up online. I went off to explore, came back and couldn't save, despite having beaten a hoard prior to exploring. I go out to see, and it''s a zombie with a back pack who is the same character as I am. So naturally I clobber them t death and to my joy find a crapton of bullet from the corpse!
I assume this was another player who died online or something? Came up with a name and everything so I guess. What facilitates these events though, why did I have to kill another player's zombie?
