This documentary series provides a look behind the scenes at GRASSHOPPER MANUFACTURE. It is separated into two formats: THE DEV ROOM, in which a random designer is briefly quizzed on the spot, and Creator’s File, in which SUDA51 gives a deeper dive into his experiences in the video game industry. The series is recorded in Japanese and released on YouTube with the option of English subtitles. The earliest episodes censored works-in-progress, although future episodes were more lenient, such as showing the 3D render of a monster that has yet to appear in GRASSHOPPER‘s published work. The most recent episodes have returned to obscuring gameplay footage, as GRASSHOPPER‘s next title presumably reaches its final stages of development. “THE DEV ROOM 03” also contains a brief conversation about a card-based minigame in development at the studio.
