On #7, the alert that you have teamkilled someone is no longer there. It used to come across the screen in red/orange lettering saying to watch your fire. The only downside is that it's hard to keep track of your teamkills because if you don't see the kill feed, you won't know if you tk'd or not. I ALWAYS say sorry if I teamkill someone, but I think I've been missing some and I don't want to cause those players to tk me back because they thought it was intentional.
