Obviously, you will need 4 controllers for this one. You can't be quick enough to punch all 3 with only one character. What you have to do is punching 2 characters at the same time with 2 different controllers and then quickly punch the remaining one with your main character. Don't start your game in meadow because in this arena the game ends after only 1 kill. My favorite one is the sushi bar because it is the smallest arena.
