Guidelines on how Valve wants manufacturers to use the SteamOS branding, implying they may be in talks for people to ship products with it pre-installed. Which may also imply they’re getting somewhat close to a release of a generic installer that’ll work on more hardware as I think I remember reading they wanted to get it to hardware vendors first

There’s a port of the game that runs on Quest and Pico VR headsets that’s dope as hell. Officially comes with the demo version and requires pulling files from the PC version to get the full game which is a bit difficult to get legit at this point, though there are other ways. https://github.com/lvonasek/PreyVR

I mean, until the update comes out it would need to be indefinite, you can’t know what needs to be changed to even give an estimate until it’s out. Could be anything from a simple five minute fix to starting from near the beginning, may need dependencies updated, etc
