You're invited to the Euro 2008 playing this game of football ... without feet, just by using his head to throw the ball over the net into the opponent and score points if it does not to return. It looks like volleyball with the head that replaces the hand. Try to beat the team of France!
In the main menu, select Options to define your keys (as predefined ones are not very practical). To set your arrow keys, Left click on the buttons (left), Right (right) and Jump (jump) and press the button replacement. Choose single player mode (single player) or multiplayer mode (Multiplayer), then the Euro 2008 or a friendly game, then your team. Finally it's up to you ... with the head.
