The Gridiron ball is used in the Gridiron game mode. It will spawn at a middle point in the map. It grants the player a minor health boost and extra speed, and can be thrown once picked up. It can also be used as a melee weapon, and will kill enemies in one hit. If thrown into the objective, 1 point is awarded, but if it is "dunked", then it 2 points are awarded. It is possible to pass the Gridiron ball to other players.
The Gridiron ball also appears in Headquarters. The ball is hidden in three different locations inside the Headquarters and can be picked up by the player. It can be thrown and passed to other players. After picking up all three Gridiron balls, the player will complete the challenge and will be granted with "Baller" Calling card.
