Following the death of actor Lance Reddick in March 2023, Guerrilla Games has confirmed that the character Sylens will be recast in the upcoming Lego Horizon Adventures. Reddick, known for his roles in Horizon Zero Dawn and Horizon Forbidden West, was beloved for his portrayal of Sylens, a complex character who allied with the protagonist, Aloy. Guerrilla's senior world artist, Lucas Bolt, stated that while Sylens will appear in the Lego spin-off, a new actor will take over the role, though their identity has yet to be announced. The decision to recast Sylens reflects the character's importance to the franchise, with speculation that the new voice actor may also reprise the role in future Horizon games. Reddick's passing, attributed to coronary artery disease, has left a significant impact on both the gaming community and the industry at large, with tributes paid across various platforms. The Lego Horizon Adventures is set to launch on November 14, 2023, and will feature other original voice actors from the Horizon series.
