To be able to play the hidden two-player games you must first beat the normal game on any difficulty level. Getting bronze silver or gold in the missions is not necessary to unlock the two-player missions on the Bonus Missions Screen. Unfortunately once unlocked in you must still get gold in every level of the normal game to play the bonus level. In Capture The Flag you and a friend battle it out in the skies of Naboo. Rules follow basic Capture The Flag rules where players try to steal an opponents "flag" and return it to their own airspace.
