This is probably the only Neptunia game that has interesting story I have ever played to date.

- New characters.
We got:
Uzume Tennouboshi/Orange Heart, as reference to Dreamcast console.
The Gold Third: B-Sha (ref. to Bandai-Namco), K-Sha (ref. to Konami), C-Sha (ref. to Capcom), and S-Sha/E-Sha (ref. to Square-Enix).
The enemy, Steamax, as reference to Steam, probably.
Sadly, the Makers from Rebirth game is not present (Falcom, Tekken, etc), but other Makers can join via DLC, named Million Arthur, God Eater, and Nitroplus.
- New combo system.
The combo here is little different from Rebirth games, where in this game there's a feature called Combo Trait where if a certain condition is fulfilled, executing a move will increase its damage. Also, each weapon has different combo slots so different weapon means different combo. This gives another take to creating a combo effective enough for defeating your enemies.
- New CPU Form: the Next Form.
As you can see the from the game screenshot, each CPU has their new form where you can unlock as you progress the story. It's kinda cool where they transform for the first time.

If you've played through Rebirth 1-2-3, this entry is (sort of) the continuation of the Rebirth series and a must for Neptunia fans.
