It features 73 teams' countries.  Each team enters a "Regional Qualifying Round Final" where it plays a team it actually played in the 1998 FIFA World Cup qualification.  For example: Spain would face Yugoslavia, an opponent it actually faced in its qualifying group.  Or Italy would face Russia, an opponent Italy faced in the UEFA play-offs.  If the player beats the opponent, it goes to a group much like the real life World Cup.  In fact, the team faces opponents that were actually in its group.  For example: Mexico would face the Netherlands, Belgium and South Korea.  It is a re-make of "Super Sidekicks 3".  However, animations and designs were exactly the same.

Its slogan is "We got the kick".
