I've already made a thread for this game and had already updated it with information about this updated.
Perhaps I phrased it poorly in my notes about the update but you actually can NOT kill players yet. You can shoot other players but they wont ever die. You can only kill the non player characters.
EDIT: I just realized this is the thread being used for the front page. It makes sense for it to exist then lol. The other thread I have going is filled with info on the past releases and isn't really suited for a news post.
