So I recently re-downloaded the game after not playing for, I think, three or four years, and I can’t seem to find the LCS cruise server. What happened to it? That’s the whole reason I used to play this game, and now it’s not there anymore. I was wondering if it’s just down right now or did they shut it down, and if it’s shut down, is there a replacement one that’s similar or is that just not a thing anymore?

It's online, maybe you have empty servers filter on.
