To make the endzones hidden, start a Play Now mode match. When you reach 
the field selection screen, set the game length to fifteen minutes, make 
the weather overcast cloudy, precipitation high, and temperature -20 
degrees. If done correctly, in the upper corner should be a picture of a 
cloud with heavy snow. Start the game and by the second quarter there 
will be so much snow that the endzone lines and all other white lines 
will be gone.
