Recently, eagle-eyed gamers spotted a QR code sneakily hidden on the back of the exclusive Cyberpunk 2077-themed Xbox One controller, which will be releasing alongside a similarly themed console. Previously, scanning the QR code would simply lead to a pre-order page for the game itself but, about a week ago, CD Projekt RED changed the code's destination without making any sort of official announcement.

Now, when scanned, the QR code directs fans to an unlisted YouTube video on the official Cyberpunk 2077 channel. The video contains a brand new song, "The Ballad of Buck Ravers," performed by in-game band SAMURAI (aka real-life band Refused).

"The Ballad of Buck Ravers," is an intense anti-tyranny pro-revolution track about the desperation of life as a "wage slave" and the need to rebel. It is the third SAMURAI track revealed so far, with the other two ("Chippin' In" and "Never Fade Away") being officially listed on the game's YouTube channel.

CD Projekt RED is no stranger to hiding "Easter eggs" in marketing and promotional materials for Cyberpunk 2077. The hidden messages began with the game's E3 2018 presentation, and have continued in the form of clues inside concept art, codes on the pre-order page, and even a series of physical riddles and puzzles sent to various Cyberpunk 2077 content creators.

Hopefully, this musical "Easter egg" will be enough to keep fans sated until June 25, when a unique "Night City Wire" broadcast will reveal more information regarding the game. Initially, the "Night City Wire" was scheduled for earlier in the month but was delayed to honor the Black Lives Matter movement and calls for justice for George Floyd and Breonna Taylor.

Cyberpunk 2077 is currently scheduled to release on September 7 for PlayStation 4, Xbox One, and PC. Rumors indicate that the game will also be coming to Stadia, Xbox Series X, and PlayStation 5.
