The mod has been consistently going since 2005, so they’ve had a lot of time to build up assets! There’s a lot of snazzy new features, but everything still aims to integrate with Freelancer’s original setting and lore. Mixed success, but it works more often than not. There’s a community Discord if you wanted to take a look around or ask questions.
Don’t know if you’ve tried this before, but there at a few guides for getting the mod working on Linux. This might help?
