Mobile Suit Gundam: Battle Operation Code Fairy - Vol. 1 is a single-player action RPG developed by Bandai Namco Entertainment and released in 2021 for PlayStation 4 and PlayStation 5. The first installment in the Code Fairy series, it covers Episodes 1 through 5 of an original story featuring characters created specifically for this title. The gameplay mechanics carry over from the multiplayer-focused Mobile Suit Gundam Battle Operation 2, adapting that game's controls and combat feel into a dedicated single-player experience built around scripted story missions. Rather than the open-ended online battles of its predecessor, Code Fairy Vol. 1 structures its content around narrative progression, placing the original cast at the center of mission-based mecha combat set within the Gundam universe.
