The break in this monotony comes in the form of Game Changers, thirteen separate powerups that can completely change the action on the field in surprising ways. These include freezing one enemy in his tracks, adding your entire offensive or defensive line on the field or adding decoy balls during a pass play. Powers can only be triggered after a play has been selected, and can only be held onto for a four-down sequence. You also can't stockpile game changers, collect them based on your play or gain items on the field. Instead, your team will randomly have a chance to acquire a game changer at the start of each down.
