Defunct online multiplayer you never got to try? (PC only)

Are there any PC exclusive games you love but with multiplayer that has since been shut down and you never got to try it? As I recently have gotten back into the decade-old FPS classics Counter Strike Source and HL2 Deathmatch, I've been looking for other older games that will run on my rinky-dink laptop, but I've noticed that a number of titles, some very highly regarded, no longer have online support for their multiplayer, with no fan-workarounds, either, which inspired me to make this thread.

(NOTE: This thread is ONLY about games that do NOT currently have fan patches/workarounds for online support.)

I can think of a few off the top of my head:

-Far Cry. I've heard that the multiplayer was arguably even better than the single player mode, but the servers have since been shut down and sadly unlike crysis there doesn't seem to be any workaround for it. Plus, like a lot of open-world FPS it doesn't feature bots, so there's no way for me to experience it.

-Devastation. The gameplay and audio design remind me a lot of Counter Strike, another tactical multiplayer FPS, and since it featured a robust, ambitious physics system along with some of the best interactivity of any FPS at the time I am extremely interested in playing both the single and mutiplayer modes, but I've heard that the online servers have long been dead and there doesn't seem to be any workaround. The game is also not available digitally and will not run on Windows 10, another huge drawback for the game in general. What a bummer.

-B.R.E.E.D. This is another obscure older PC exclusive FPS that I've been wanting to play for a while now but haven't yet. I've heard that it has online support for its multiplayer, but I would be baffled if the servers were still up or if there are any workarounds if they aren't anymore, given its obscurity.

-Chrome. Another ambitious early 2000s PC exclusive FPS that is said to have many similarities to Far Cry, being an open ended shooter with a physics engine, which is why I'm extremely interested in playing it, since I'm a big fan of Far Cry. However I've noticed that there are no workarounds for its defunct multiplayer, which is a pity. (EDIT: did some research and it seems that the online servers are in fact still up, which is baffling considering that it was a 2003 game. I have my doubts if this is true...)

-Star Wars Battlefront 2004. One of my all time favorite Star Wars games and easily my favorite Star Wars Battlefront game, the first Star Wars Battlefront for PC from 2004 tragically does not have fan servers up as of this post. The official Game Spy servers it used were shut down years ago with the demise of Game Spy. Someone needs to do something about this! The PC version is the only version of the game that supports 64 player multiplayer, and since it was recently released digitally on PC for the first time ever there's all the more reason for unofficial servers for it to be set up.
