For completionists, Persona Q2 offers various in-game achievements and collectibles. Here's how to aim for 100%:

- Complete All Requests: Regularly check the Request menu in the Central Cinema and complete every available side quest. Some requests unlock new features or provide unique rewards.
- Collect All Film Strips: Thoroughly explore every corner of each labyrinth to find all hidden Film Strips. These unlock all Memory Events, providing additional lore and character interactions.
- Fill the Persona Compendium: Fuse and register every Persona available in the game. This requires extensive fusion and often specific fusion combinations. Check online resources or in-game fusion calculators for guidance.
- Defeat All F.O.E.s: While many F.O.E.s can be avoided, defeating each unique F.O.E. type at least once is often tied to achievements or material drops for powerful equipment.
- Max All Character Levels: While not strictly an achievement, having all characters at max level (99) will make all challenges trivial and is a common goal for completionists.
- Unlock All Unison Attacks: Experiment with different party compositions to unlock all unique Unison Attacks. These are often tied to specific character pairings and story progression.
