Nintendo has confirmed that the new Zelda: Breath of the Wild game is co-developed by Monolith Soft, who have over 100 developers working on the game. Which is the majority of their staff.
“People from Tokyo and Kyoto are working together on this. There is a team of over 100 [from Monolith] helping work on this project, and their work has really been helpful” said Nintendo’s Shigeru Miyamoto to GameInformer.
This wouldn’t be the first time Monolith has helped Nintendo on a Zelda game — they also helped on Skyward Sword for the Wii.
Monolith’s most recent game was the Wii U exclusive Xenoblade Chronicles X, so the company is pretty familiar with the console and its development tools.
Zelda: Breath of the Wild looks like the biggest Zelda game ever — what we saw during E3 represented just 1% of the final game.
Nintendo has already confirmed that the game is much larger than Twilight Princes. The world in Breath of the Wild is 12 times bigger than in Twilight Princess.
