There's a delightful musical Easter egg hiding in the newly released Cyberpunk 2077: Phantom Liberty that will excite fans of The Witcher 3. Harking back to CD Projekt Red's own popular game, The Witcher 3, the developers have cleverly concealed this fun surprise. In one segment dubbed Lucretia My Reflection, we come across a wall-mounted phone essential for contacting a character named Solomon Reed. However, aside from its primary purpose, the phone has another intriguing secret. If you input a particular set of numbers - 5745552377, to be precise - scribbled on a nearby post-it note, the familiar theme of The Witcher 3, The Trail, begins to play in the background. Moreover, our punk rock legend Johnny Silverhand reappears, gleefully listening to the tune. At the end of the performance, he gives the audience a contented smile and a thumbs up, signifying appreciation. The Phantom Liberty DLC landed this week, years after the original game's release, receiving overall positive reviews. This unexpected crossover offers fans a warm wave of nostalgia, reminding them how greatly Cyberpunk 2077 has evolved since its initial launch. This playful nod to The Witcher 3 just adds another unique touch to the expansive and immersive universe of Cyberpunk 2077: Phantom Liberty.
