Complete all 10 pages in Game Breakers.

This game mode is under the Normal menu (the other option to the right of Regulation mode). The idea is simple: successfully score on the play(s) and get enough cash to move on to the next page. 3 strikes and you're out, but you get a few continues as well. This is hands down the toughest achievement to unlock in this game. You have to successfully execute 10 pages of plays with minimal errors. The best advice I could give is: practice, practice, practice.
