Deep Silver and 4A Games have just revealed Metro Exodus Enhanced Edition and they've confirmed that Linux support for Metro Exodus is still happening.
A lot of the work they're currently doing is on supporting the newer consoles, and while it already supported Ray Tracing, they decided to do a "radical" overhaul of their proprietary 4A Engine to improve the Ray Tracing found using more advanced and better techniques.
For the PC version (they probably mean Windows), it will be free for anyone who owns Metro Exodus as a standalone application and will release "later this spring". Thankfully, Linux has not been forgotten about. After confirming their continued commitment to release Metro Exodus for Linux in November last year, this big announcement also once again confirmed that the Linux version will appear a bit later this year (sometime after March when it lands for macOS).
Last but not least – back in November, we also confirmed our commitment to Mac and Linux versions of Metro Exodus.
We’re happy to confirm that the Mac version is expected to release on the Mac App Store, Steam, and Epic Games Store in March, with the Linux version set to follow a little later in the year on Steam!
Hopefully the Linux version won't miss out on some of these Ray Tracing boosts. Vulkan now has official Ray Tracing support so it would be great to see it in properly.
