If you listen closely to the music being played in the Divine Beasts, you can make out Morse code for "S.O.S." This is very likely a distress call the Champions made when they were attacked by the Ganon Blights 100 years prior to the start of the game.

After Link recalls the 12 memories, Impa shows him a picture of the 13th memory located east of Dueling Peaks Stable. If Link takes a photo of the picture with his Shiekah slate before going to the site, he'll take it out and look at it as he did with the other 12. If not, he recalls the memory while keeping the Shiekah slate put away.

The geography of Tarrey Town featured on the Sheikah Slate's map actually changes as Link progresses through the side-quest "From the Ground Up".

If timed correctly, it's possible to shoot a horse with ice arrows and have it keep the "frozen" texture that covers its body when Link drowns in deep water from having no stamina immediately afterwards. When Link respawns, the player can find the frozen horse in motion and can ride it like a normal horse, however putting the horse in a stable returns it to normal.

During a demo at E3 2016, the Shiekah Slate had the ability to reveal an enemy's Hit Points. To do so, the players would hold the Wii U gamepad up to the screen and hold the cursor at the enemy who's Hit Points they want to see. This was removed because of how cumbersome it was and how it was almost no help in helping players on how to analyze enemy camps.

Inside the last room in the Sword Monk's Shrine, after completing the Trial of the Sword, there are seven monks with their arms in positions representing poses of the seven Sages in The Legend of Zelda: Ocarina of Time. Zelda's pose is during the final battle with Gannon and the other six Sages' poses are from inside the Chamber of Light after defeating the corresponding temples to release the Sages.

In The Legend of Zelda: Breath of the Wild - Making of a Champion art book, an excerpt states Link's hometown is likely Hateno Village. An image in the book also seems to imply that the house for sale was Link's old house.

In the book The Legend of Zelda: Breath of the Wild - Creating a Champion, concept art of Link's family is omitted from the English version and is found in Master Works, the same book in Japan. Concept art shows Link's father, a knight mentioned in game, and his sister.

The Korok seeds Link finds are actually Korok excrement, best exemplified by the reward Hestu gives Link out of friendship for collecting all 900 Korok seeds in the game; "Hestu's Gift", a large pile of Korok excrement that "smells pretty bad".

Just north of Hebra Tower, a geometric plane sticks out of the mountainside that prevents Link from climbing any higher and can only be seen from above.

A save glitch exists that allows a player to exit the Shrine of Resurrection without the Sheikah Slate; without the Sheikah Slate, the player cannot warp and does not have a map but can use runes, control Divine Beasts and interact with terminals. Time is also stopped, preventing Blood Moons.
If the player desires to obtain the Sheikah Slate later, he/she can by returning to the Shrine of Resurrection.

Inside the game's files is a picture containing Link doing a pose next to Zelda. What's interesting about this is that Link's "Hero of the Wild" hat and tunic were changed in the final release. The length of the sleeve and cuffing were also shortened in the final version; it was rolled up slightly and thinner as seen in the photo. The gold trim on his hat was subdued green in the final release, likely because the 8-bit Link amiibo had a similar form.

The "Korok seeds" in this game originally started out as being rock-like objects that players were meant to discover throughout their adventure. These rock-like objects used the Master Sword pedestal asset from The Legend of Zelda: Skyward Sword.

An ice cream cone model is used as a placeholder item that displays as an elixir with no effects.

At the northern entrance to the Bridge of Hylia, there is a missing portion halfway up the column, and when Link climbs inside, the cel shading filters do not work.

There is a sprite of an Octorok from the original The Legend of Zelda located on the bottom right of the Trousers of the Hero.

Breath of the Wild started it's development in 2011 as an open world Zelda Game for the Wii U, originally planned to be released in 2015. The release was later delayed to 2016 after developers conceived of new gameplay options they wanted to include. This release date was then further delayed to 2017 so that it could be released simultaneously on Nintendo's next platform, the Nintendo Switch.

Monk Oman Au's name and the shrine of Oman Au are both anagrams of Aonuma. Eiji Aonuma is the video game designer, director, and producer who works for Nintendo as the series producer and manager of the Zelda series.

You can hear the recorder sound from the first The Legend of Zelda in shrine areas.

The game is the first 3D game in the series to include manual jumping, though this feature was first planned for The Legend of Zelda: Ocarina of Time.

In shrines, after placing the Sheikah Slate to download runes, Hylian text begins to run down the stalactite above it. Portions of the text have been translated to read "NOW LOADING DO NOT TURN OFF YOUR" and "ALL YOUR BASE ARE". The latter phrase is a reference to Zero Wing, a 1989 game infamous for its horrible English dialogue that spawned the iconic phrase "All your base are belong to us".

According to series producer Eiji Aonuma, to date, The Legend of Zelda: Breath of the Wild has a larger number of people working on the game than on any of Nintendo's previous titles.

The opening scene, Spoiler:when Link emerges from the cave where he awakens and overlooks the valley from the Great Plateau, was made to reference the illustration of Link overlooking the cliff from the original The Legend of Zelda.

According to Aonuma, the game was subtitled "Breath of the Wild" instead of being based on a character or an item because the development team wanted the title to reflect the nature and expansiveness of the world in the game.
