For this Achievement, you will have to win at Lambeau Field – the Home of the Green Bay Packers – in snowy weather conditions. You don't have to play against the Green Bay Packers, though.
Plug in 2 Controllers, go to „Play Now“ and let Controller 2 select any team as the home team – be aware, the home team is always on the RIGHT side of the screen. Move Controller 1 to the LEFT side – the Away Team.
Now press to be taken to the Options Screen. Press two times to get to "Advanced Settings", scroll to the bottom and select "Heavy Snow" as Weather. Let Controller 2 (Home Team) get beaten by Controller 1 (Away Team) and this Achievement will be yours.
NOTE: This Achievement will unlock after you finish the game, don't be alarmed if it doesn't pop up immediately after you've fulfilled all the requirements. Make sure to check that the difficulty and quarters are set to fit the requirements.
