Kingdom Hearts Collaboration: Gummi Ship Campaign

Kingdom Hearts Collaboration: Gummi Ship Campaign, also written as FINAL FANTASY Record Keeper × KINGDOM HEARTS Union χ [Cross] Collaboration Event – Gummi Ship Minigame, was an online minigame for smart devices based on the Gummi Ship mini-game from Kingdom Hearts II. It was available during the "Final Fantasy Record Keeper × Kingdom Hearts Union χ [Cross] Collaboration Event" from February 10 to 16, 2018, a crossover campaign between Final Fantasy Record Keeper and Kingdom Hearts Union χ. The goal of the campaign is to collect points to unlock in-game rewards for both games.

Mechanics
The game has two game modes, Easy Mode and Hard Mode, each featuring 2 missions. After selecting a mission, players can choose a Gummi Ship model. At the start of the campaign, only one model was available, but one model was added each day of the campaign, up to a total of six, which needed to be unlocked by collecting medals.

The Gummi Ship can be controlled by dragging your finger on the screen. It shoots automatically. When releasing your finger, it will shoot lasers at locked-on targets. Enemy ships drop medals and HP orbs. At the end of the mission, your high score is determined by the number of medals collected and Gummi Ship used.

List of in-game rewards
These rewards will be distributed to all players of Kingdom Hearts Union χ and Final Fantasy Record Keeper when the total amount of points collected by all participants reaches certain milestones.
