To bump this up, team-killing is not my thing anymore. We're here to play against rivals, not your allies. I'm sure to level up here, nobody likes team-killing here at PSN.
why team kill sure it seems fun to you but other people are trying to play the game for the game and when you do it. it usally dosent end well if you arnt very good keep trying i comeplety stink lol but hey atleast i dont give up. have respect for other players on your team if you arnt good help them out the best you can..
