Keeping true to the series tradition of introducing new characters, the game marks the return of classic fan favorites from Sega's Virtua Cop and Skies of Arcadiaseries.

The handheld versions, however, will continue to use the tactical, turn-based system from the first two games. The console versions have been built from the ground-up using Square-Enix's Luminous Studio engine, which debuted on Final Fantasy XV. It boasts a reinvented battle system and expanded roster from the previous games, implementing the open-world action-battle system inspired by the Kingdom Hearts and latest Final Fantasy entries. PXZ3 marks its series debut on home consoles as well as the first game to feature Square-Enix characters. It is the direct sequel to Project X Zone 2, the eighth game in the Namco X series and the sixth and final entry in the Japan Six.

Project X Zone 3-D, or simply known as Project X Zone 3: Worlds in Peril under the handheld versions, is a crossover Action/Tactical Role-Playing game developed by Square-Enix and published by Bandai-Namco Entertainment in conjunction with Sega and Capcom.
