Found another little gem, this time called
TSA_Outpost. Looks like a nifty little lunar map with a cool-looking extraterrestrial landscape, including crystal objects of various sizes poking out everywhere, some particles in the air, a small base in one corner, a bunch of cool uses of particle effects, and other stuff. I saw ELH & RDL guys playing it earlier, but when I asked, apparently RDL "Found it on the internet," so it may not be getting updated anymore.
There seems to be a bunch of these maps related to this "world of battletech" thing which I think I saw mentioned in discussions around the planetary league alpha, apparently like it's own mini MWLL league or something. Maybe doing some digging related to that might uncover something...
