I've been trying to get a Battletech fix while waiting for some kind of accessible Megamek prototype, so decided to investigate the old Battletech muxes. It's a very strange feeling wandering around a bunch of empty real estate.
I'm currently the only Capellan Confederation player on Frontier Mux. As near as I can tell I'm the only player at all. THere are no officers, no one to give me orders or set mission objectives. I managed to get killed by an AI-controlled unit but have no real idea what I was doing. There are two other players who show up on the Who list, but they seem to be automated, or perhaps admin accounts.
THis experience is a little sad, because the BTMUX implementation is clearly a labor of love and seems to include a ton of mechs and equipment. I don't know how good the AI is, but it's clearly not any substitute for other players. I wonder how long the games at btmux.com will keep running before they just go down one day.
For anyone interested, FrontierMUX is at btmux.com port 5555. All commands are still operational. The wiki doesn't seem to be reachable from the main web page anymore, but you can still find it on the Internet Archive.
