BACKBREAKER

Pretty self explanatory : go online and win a game. Nobody plays this game anymore, so you may want to boost it.

And as you're at it, don't forget to take a custom team with you to get the related achievement.



Also, quitting won't work, you won't unlock the achievement if your opponent quit before the end. You will have to play the full game. Set up the quarters to one minute and use time killing methods and you'll get there fast.
