The following entails the contents of the main menu in Final Fantasy XIII-2.
In the Paradigm Pack menu, the player can assign up to three different monsters to the Paradigm Pack layout. 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. 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 of materials they require in the Crystarium. If a creature has a full Feral Link gauge, its border in the menu will glow green.
The Customize menu allows the player to set and tune their paradigms. Up to three different layouts can be saved and loaded at will.
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.
The Monsters menu displays all of the monsters the player has captured, which may be used in Paradigm Packs. Here, the player can view their stats, traits, and abilities, and dress them up with various adornments. They can also be infused into other monsters, giving them additional abilities and passive abilities.
In the Equipment menu, the player can equip Serah and Noel with weapons and accessories. 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 synthesized passive abilities that also take effect during battle.
This option allows the player to switch the party leader between Serah or Noel, which is preserved after battles. It is not accessible during certain periods.
The Status menu displays stats, abilities, and passive abilities for each party member and monster.
In the Inventory, the player can view and sort the items they possess. Key items and specialty items are used automatically at specific points in the story, while items are used during battle, weapons and accessories in the Equipment menu, components at Chocolina's shops, monster materials in the Crystarium menu, and adornments and monster crystals in the Monsters menu. Unlike in Final Fantasy XIII, an exclamation mark will not appear next to newly-obtained items.

The Bestiary displays a list of monsters the player has slain during the game, showing an animated model of the target and their stats, including weaknesses and strengths. Unlike in Final Fantasy XIII, an exclamation mark will not appear next to new enemies.
In the Fragments menu, the player can view tidbits of information that are uncovered when obtaining fragments during the game. It functions similarly to the Datalog section in providing additional information on people, locations, folklore and legends.
In this menu, the player can turn fragment skills on or off. Fragment skills are obtained from the Mystic in Serendipity by finding more fragments.
This displays a map of the current area, which can also be accessed by pressing / on the field.
Added in with a post-release patch, the Outfits menu allows the player to change the in-game appearance for Serah, Noel or Mog. Outfits cannot be obtained from the game itself and must be downloaded.
