Rez Infinite features several hidden elements and unlockables that extend the game's replayability:

- Lost Area: This secret Area is typically unlocked by achieving a high score or completing the game on a higher difficulty (e.g., Trance Mission). It offers a unique visual and auditory experience.
- Beyond Mode: After completing the main game, you'll unlock 'Beyond' mode, which allows you to replay the game with different visual filters and settings, offering a fresh perspective.
- Avatar Forms: Achieving certain milestones (like completing all Areas, getting high scores, or finishing Trance Mission) can unlock new, visually distinct avatar forms.
- Sound Mode Extras: The Sound Mode often contains hidden tracks or options that become available after completing the game or achieving specific feats.
- Direct Assault: Unlocked after completing an Area, this allows you to jump directly into any Area for practice or casual play.
Experiment and explore to uncover all these secrets.
