Create and save a game plan - the new prioritization engine that brings up plays in the streamlined GameFlow mode - and when you pop in the retail disc on Aug. 11 you'll get the 5 Gamerscore/Bronze Trophy "Master Strategist" honor. That's not all. Downloading and playing the demo delivers the unique Jets Stadium card in Madden Ultimate Team - a game mode that ships free with this year's title.
Further, in years past the game demo delivered no audio; this year you can hear Chris Collinsworth and new play-by-play man Gus Johnson calling the action.
The demo goes out over both console download serveices on July 27, and will feature the Indianapolis Colts at the New York Jets, a matchup chosen by fan voting earlier in the year. The game will be played with 5 minute quarters in clear weather under afternoon skies. The game's four different difficulty levels will also be available.
