Yeah, looking at the weekly recap stream where they actually talked about it, it is indeed a new anti cheat like you mention that (according to their own statement) is still more effective than "what they have now" (that being eac). https://youtu.be/nIay2Aq2ars?t=702 Apparently they want to do a stream again with the team from Faceit talking about it in more detail.

Looking through their Discord it seems there hasn't been any details yet regarding how this is going to work if this indeed is real. I highly doubt Faceit would want to vastly weaken their effectiveness on Linux in the same way EAC and Battleye do by running it as a user process. Even if just speculation, that would mean a kernel module that would need secure boot enabled (though even that is not required for the windows variant in battlebit) with a signed kernel and so on and would only work for specific distros?
Metro 2033 Redux and Last Light Original and Redux have Linux native versions on Steam already, just not the original 2033. Granted, the original games are not even purchasable anymore though, only Redux.
