According to Walter Isaacson's new book "Elon Musk," a biography of Musk, Musk once visited the developers of CDPR with a gun and asked for a cameo role in "Cyberpunk 2077."
Walter Isaacson said that Musk had a strong desire to make a cameo in "Cyberpunk 2077" and that he had a soft spot for the game before its release. So when Grimes (Musk's girlfriend) was recording the voice for the character Lizzie Weisz in "Cyberpunk 2077", Musk appeared in the recording studio with a 200-year-old gun in his hand.
According to Grimes, all the staff were sweating at the time, and she thought the gun might be a replica pistol on Musk's bedside (Musk had posted a photo on Twitter). Musk explained to Walter Isaacson: "I told them I was armed but not dangerous."
Walter Isaacson believes that the reason why Musk focuses on "Cyberpunk 2077" is because the Relic technology appearing in the game is very similar to Musk's company's brain-computer interface technology Neuralink.
Interestingly, after this incident, Musk may actually get the opportunity to make a cameo. At the beginning of the company route in "Cyberpunk 2077", players will encounter an NPC very similar to Musk in front of the bathing pool.
