Well, Unreal Fortress, a very old but very awesome mod for Unreal Tournament has a new server, after being 'dead' for about a year.

So, if anyone is looking to play with a tight, but awesome community, get yourself a copy of Unreal Tournament and try it out ($5)

If anyone previously played it, HELLO! ^^

Yeah.
So.
Clicky
It's really awesome. It's basically Team Fortress Classic for Unreal, but some parts are spiffilicous.
