New Features in ƒ

Gameplay

• A new ☆ icon represents touch notes. To hit them, swipe the screen in any direction each time a note reaches the timing path.
• The Technical Zone is a new feature introduced at various points of each song and encompasses multiple notes in a manner similar to Chance Time. Completing the Zone awards extra points and contributes to the clear rank score. Getting a SAFE, SAD or WORST will fail the Zone and no extra points or clear rank points will be awarded.
• Notes hit with the incorrect button use the same system as the first Project DIVA game; instead of being counted as WORST, they are counted as SAFE and display off-color versions of regular hit ranks.
• The HUD has been redesigned:
  • The life gauge changes to a star icon when entering Chance Time and instead counts successful note hits (COOL or FINE).
  • The progress bar at the bottom of the screen indicates the current clear rank score and changes color when new ranks are attained.
  • When all the notes in the song are hit successfully, the last note hit will trigger a "PERFECT" popup before the results screen.
  • Notes hit with the incorrect button display a red COOL, dark-blue FINE and black SAFE and SAD with crooked letter arrangements.
• Chance Time now ends with either a "Success" or "Failure", similar to the Technical Zone. A large ☆ note follows the end of every Chance Time, and will be grey unless a certain quota of notes is reached before the ☆ note appears (in which case it appears golden). Hitting the final ☆ note when it is golden will mark the Chance Time as successful. Succeeding at Chance Time will contribute to the clear rank score and display an alternate ending to the background PV.
• Each PV has two endings: a normal ending and an alternate ending with sound effects, both of which can be seen during Play mode and PV mode. The alternate ending is unlocked for PV mode by successfully clearing Chance Time, as explained above.
• Getting a COOL at the start of a hold note is worth double points (points given at +20 intervals).
• An additional 200 points are awarded for every simultaneous press of both the D-Pad and the Action buttons when hitting a "W" arrow note. The points are not given if one of the buttons is already held prior to hitting the arrow note.
• Each song has separate audio tracks, akin to the first Project DIVA, the Dreamy Theaters, and Arcade. Getting a SAD or WORST will temporarily mute the vocals until a note is hit successfully. While the vocals are muted, the singers in the background PV will cease mouth movement animations.
• Up to three Vocaloid characters can appear in a single song's PV, as opposed to the previous two. The song "Continuation of Dreams" is an exception, featuring four characters at once (but only one can be modified). Edit Mode only supports up to three characters.
• There are two types of modifiable PV characters: Vocal and Guest. Vocal characters sing while Guest characters merely make an appearance.

Song Select Menu

• Difficulty modes are now tabs, selectable from the main song select menu. Press left or right on the D-Pad or the L or R button to select difficulty.
• The song list can now be sorted by: Difficulty (Star Rating), Alphabetical Order, or Default.
• Clear ranks are now displayed as an icon next to each song name: S for Standard, G for Great, E for Excellent, and a crown for Perfect.
• Difficulty ranking now features half-stars is ranked on a scale of ten stars.

Characters and Modules

• The game features 71 new Modules, designed by various artists from the Vocaloid community.
• All character models exhibit higher polygonal and textural detail than the previous PSP games, advanced facial expressions (such as crying with tears) and physics.
• PVs feature more interaction between the Vocaloid characters and background characters, such as dancers or animals.
• Characters who previously did not feature the 'kyaa' expression (> <) in previous Project DIVA games now have this expression available.
• Character outfits can now be modified with 97 various accessories.
• Sakine Meiko is no longer a standalone character and is now a module for MEIKO. Akita Neru and Yowane Haku are no longer in the game, but have been announced as future DLC along with Kasane Teto.
• Modules from the previous Project DIVA games are not available, save for the Append versions of Miku, Rin, and Len.

DIVA Room

• Characters can now be interacted with using the touch screen and will react to various actions by showing affection or irritation.
• A gauge in the bottom-right of the screen gauges Affection level. A character's Affection level rises through petting using the touch screen, participating in minigames, placing items that can be interacted with in the room, or giving Presents.
• Some Present items trigger a DIVA Room event where the characters have dramatic moments.
• Some items function as Gadgets and offer useful functions, such as an alarm clock and a kitchen timer.

Modes

• An Augmented Reality feature allows superimposing of "life-size" characters into photos of the real world. Photos are saved to the PlayStation Vita's photo library. The characters' size, pose, and expression can be modified with a wide variety of options.
• The Augmented Reality feature also allows "live concerts" by tracking an AR Marker with the PlayStation Vita's camera to display Miku dancing and singing in the real world in real time. AR Live includes four exclusive songs, which aren't playable in Rhythm Game Mode, three of which are featured in the first Project DIVA game. This mode also allows photo-taking.
