Kingdom Hearts 2

The following is a list of things needed to get 100% in Kingdom Hearts 2, the list is not in detail, however there will be more additions to KH2 that display how or when you can do these things to get 100% of the game file.

Obtaining Abilities

Throughout the game Sora will obtain various abilities as he gains levels and encounters certain areas. You will also be able to learn new abilities via the use of your Drive forms, these abilities are called Growth Abilities. These abilities are things like High Jump and Glide. All abilities are required to complete the game.

Complete all the Worlds

Ignore the fact that you can skip worlds, you will need to visit every world usually twice at least to unlock all of the events to complete it. Most of the worlds are required to continune in the story, however some can be skipped but will effect your overall complete percentage. Completeing the worlds will also include doing all of the mini-games, collecting all of the treasures, finding all of the maps, and meeting all of the characters.

Items

In addition to finding all the items in the game you also need to collect various amounts of gems and synthesising items in order to create more items, all of these items need to be created. Doing the items is by far the most time consuming of the journal to complete.

Drive Forms

Drives and Summons included need to be mastered to level 7 with all the abilities learned on them. This will also allow you access to the Hades tournment which is also needed to complete the game.
