Zelda realizes that Hyrule must be rebuilt and that she and Link must begin the process themselves . If the player fulfills certain conditions, they unlock an alternative ending where Link and Zelda survey Hyrule and talk about rebuilding the world . </P> <P> The Legend of Zelda: Breath of the Wild was developed by Nintendo EPD for the Wii U and Nintendo Switch consoles . According to series producer Eiji Aonuma, the development team aimed to "rethink the conventions of Zelda". Following the release of The Legend of Zelda: Skyward Sword in 2011, Aonuma received comments from players who wished to see a more interconnected map to explore the locales between the gameplay areas . In 2013, Nintendo experimented with nonlinear, open - world gameplay in The Legend of Zelda: A Link Between Worlds . At the 2014 Electronic Entertainment Expo, Aonuma said he planned to reform dungeons and puzzles, two of the series' major gameplay elements, and redesign the game to allow players to reach the end without progressing through the story . As Nintendo had never worked on a modern open - world game before, they took influence from the development of The Elder Scrolls V: Skyrim . </P> <P> Prior to full development, the developers designed a playable 2D prototype similar to the original Zelda to experiment with physics - based puzzles . The final game uses a modified version of the Havok physics engine . At the 2017 Game Developers Conference, Director Hidemaro Fujibayashi, technical director Takuhiro Dohta, and art director Satoru Takizawa held a presentation titled "Change and Constant--Breaking Conventions with The Legend of Zelda: Breath of the Wild", during which they demoed the prototype . Aonuma called the physics engine in Breath of the Wild a major development for the Zelda series, saying that it "underpins everything in the world" and makes things operate in a "logical and realistic way", allowing players to approach puzzles and problems in different ways . He expanded on the difficulty in developing this system, recalling how one day during development he entered an area in the game and found that all the objects had been blown away by the wind . </P> <P> Eiji Aonuma, producer </P>
