Lenovo clarifies recent promotional image: No Halo 5 PC port. A Lenovo Legion Go S promotional image mistakenly suggested a Halo 5: Guardians PC release via Steam. Lenovo has confirmed this was an error, a mockup design, not a leak.
This leaves Halo 5 as the sole mainline Halo title absent from PC, a notable omission given the PC release of Halo: The Master Chief Collection and the 2016 launch of the Halo 5 Forge editor for PC. While fan speculation persists, and Microsoft's increased PC focus offers a glimmer of hope, there's currently no official confirmation of a Halo 5 PC port.
Lenovo's swift denial, and the continued presence of the erroneous promotional image on their site, strongly suggests the image was indeed a mistake. While the possibility of a future PC release remains, for now, gamers should temper their expectations. The future of the Halo franchise itself is also uncertain, with ongoing Halo Infinite updates and swirling rumors of a Halo: Combat Evolved remake and a potential Master Chief Collection PlayStation release.
