Gummi Missions

The Gummi Missions are a set of nine missions found in Kingdom Hearts II. Using the Gummi Ship, Sora and his party must unlock the pathways between the Worlds by safely traversing through these missions. Upon completion of a mission, the related World is unlocked and opened for play. Players can subsequently go back and try the missions again with different goals and difficulties; prizes are Gummi Blocks that they can use to upgrade existing Gummi Ship models or build their own.

Types of Missions
The original goal in each mission is simply to make it through the course alive. After the initial playthrough, Missions 1 and 2 will open up for each area. The Mission 1 goal is simple: collect as many medals dropped by the Heartless as possible before the end of the level. Mission 2 is a bit tougher, but more straightforward; in these missions, the higher the score, the better the prizes. Finally, Mission 3 will open up when you have a C rank or higher in both Mission 1 and Mission 2; these are also score based, but have much tougher enemies than found in Mission 2.

The missions have a different set of goals per area in Kingdom Hearts II: Final Mix+.

Completion of each mission in rank S will give the player a gummi ship/teeny ship blueprint. Original blueprints, which are high-power/high-defense blueprints designed from and made to look like Final Fantasy elements, can only be obtained upon completion of Mission 3.
