This is a football (American football, not soccer) game. You need to take the ball to the enemy's side of the field. You move in a group with the main player behind and 3 other players in front. Opponent players will try to stop you. They may simply bring one of your players down or hang behind him. In the latter case your group will be slowed down. To get rid of a hanging player tap Space bar repeatedly. If you main player is taken down, you lose the game.
