Halo 5: Guardians was among the games that have appeared in this week's massive GeForce NOW leak, but it seems like the game is not coming to PC in the foreseeable future.

Commenting on the leak on Twitter, 343 Industries Community Director Brian Jarrard revealed that there are no plans to bring Halo 5: Guardians to PC at this time, but the studio is aware of the demand, so things may change in the future. As of now, 343 Industries is focused on Halo Infinite, so we shouldn't expect any announcement in the near future.
