NHL 2K9

Easiest using the two controller method. Commit 2 penalities before the wistle blows for the first flagged penalty. Follow the strategy for the PIMs achievements, just use two of your players to hook/trip the same person on the other team so you'll get called for two penenties. For 2 minutes it will be 5 on 3. Just dont let the other team score and it unlocks once your players are out of the box.
