Gridiron is an American Football sports action game for one or two players.
Graphics are minimal, but functional, with the point-of-view being top-down, two-dimensional.
Opposing teams are represented by circular spots, black and orange respectively.
Playbooks for offensive, defensive and special plays are provided, with players choosing which ones to use at a given time.
Player control is via mouse in the usual manner.
On the offensive, users will start with control of the quarterback, until the ball is passed via handoff or throw, at which point control reverts to the receiving player.
On the defensive, users can choose which player to control, switching if necessary.
