The following entails the contents of the main menu in Final Fantasy XIII-2.
In the Paradigm Pack menu the player can set the monsters to the Paradigm Pack that may fit up to three monsters of the player's choice at a time. Once the monsters are chosen, the player is taken to the Paradigm section to customize their paradigms.
When in battle, the monster selected for a paradigm will appear in battle. If the player shifts to a paradigm with a different monster, the old monster will switch out and the new monster will take its place. The Paradigm Pack menu shows the monster's stats and what grade items they require in the Crystarium. If a creature has a full Feral Link gauge, its border in the menu will glow with green.
The Customize menu allows the player to set and tune their paradigms.
In the Crystarium menu the player can level up Serah, Noel and the Paradigm Pack monsters. Serah and Noel level up by expending Crystogen Points obtained from battles, and monsters level up via the use of items. The player can expend their CP to any role the character has available, and the section in the bottom right corner shows which abilities will come up next on the Crystarium path.
In the Monsters menu the player can view the monsters they have captured that may be used in Paradigm Packs. In the menu the player can view their stats and traits and abilities, and dress them up with various adornments.
In the Equipment menu the player can equip Serah and Noel with weapons and accessories. The accessories have a "weight", the stronger ones being "heavier" than the weaker ones; as the characters advance through their Crystaria they can increase the capacity on how much they can equip at once. Equipping certain accessories at once unlocks passive abilities that are in effect during battle.
This option allows the player to switch the party leader to Serah or Noel.
In the Inventory the player can view the items they possess. Items cannot be used from the menu, they can only be viewed. Key items and specialty items are used automatically at specific points in the story, items are used during battle, weapons and accessories are used in the Equipment menu, components at Chocolina's shops, monster materials in the Crystarium menu, adornments in the Monsters menu, and monster crystals are not used but can nonetheless be viewed in the inventory.
