Rainbow Six Siege Operation White Noise - Mok Myeok Tower Trailer Ubisoft US
An ornate case is present on a cabinet in 1F Bird Room. Destroying the top of the ornate case reveals that the case is connected to the cabinet and acts as a disguised opening to it, and the player can then throw a drone into the cabinet. Once inside, the drone can see several books. Destroying the books by jumping the drone on them reveals a hidden drone passage, which leads to a secret Easter Egg area.
The Easter Egg area contains a small sculpture that casts a shadow showing the cover art of Rainbow Six Siege from a flashlight near it. The "Ballistic Shield" is adorned with the "6" from the Rainbow Six Siege logo.
Multiple chibi operator busts are hidden around the map:
A chibi Smoke is hidden inside the Easter Egg area.
A chibi Tachanka is hidden under the desk at the 2F Info Booth.
A chibi Montagne is hidden on a shelf in the 2F Supply Room.
A chibi Ash is hidden inside a whiskey bottle in the 2F CEO's Office.
A chibi IQ is hidden behind a breakable surface in the 2F Gift Shop.
The name of the tower, as observed in-game and provided by official materials, is Mok Myeok Tower (Hangeul: 목멱 타워).
In 2F Supply Room, a calendar by the desk always displays the correct date.
In 1F Kitchen, a cake bearing the Ubisoft logo, with 20 candles, and the words "Happy Birthday" can be found. Destroying the cake reveals the plate, which has a barcode sticker saying "Made in Montreal" and "1997-2017". The cake commemorates the 20th anniversary of Ubisoft Montreal.
