As many of you have already noticed, Metric Racer is out now for Linux! Metric was even picked up by Gaming On Linux with a nice article written about it! Check it out over here!
It has been tested on Ubuntu 18.04, 20.04, Arch and Fedora. The only prerequisite currently is that you have mono installed. There's a how to pinned post in the Discussions as well, so if you run into any issues leave a comment there or head over to Discord!
If there's other platforms you want to see Metric on as well, Let me know and I will see what I can do! The main focus is to tune the gameplay, graphics and performance for the time being, but I do also want to get it out to as many people as possible through as many platforms as possible eventually!
