i tried. Sadly nvidia dlss plugin breaks the ability to package for Linux. Once released I might make a separate version without dlss for Linux.
Should work with wine based emulators though, know someone got that running.
Haven't tried gaming on Linux for a few years now so i don't know the steps involved anymore. Should be lots of resources out there, like https://www.reddit.com/r/linux_gaming/
Just to temper expectations though, a Chromebook might not be able to run the game unless it has a decent GPU.
No guide for wine that i have created. Might be something out there but i doubt it considering how it's only been available to download for a few weeks.
Should probably be like most other unreal games to get running. Maybe look a a guide for conan exiles or some other more recent title based on Unreal.
Hope you get it running! :)
