this guy again, i don’t think he’s entirely right in the head
Okay no problem you want

Oh god, not this shit again.
Xen is a dimension. Xen is not a habitable planet.
here i made a guide for you, dont feel bad
Xen is merely the border world. I don’t believe it represents the entire dimension.
I was trying to keep it simple enough so that meaning wouldn’t be too lost in translation.
being in xen is like being under the map in a GTA game
from what I have been reading on half life lore, xen is a world between world, its over all design is basically a large asteroid field floating in the “habitable zone” of a self illuminating gas giant. that floating part is why the gravity is less then on earth, you are on a low grave area around a “planet” that can barely hold its self together. This isn’t possible according to current believes and views in science. but it is possible some where where the laws of physics do not apply hence the boarder world thing.
will post image later, but xen is basically a large amount of asteroids floating in what looks to be a fluidic space while orbiting a gas giant.
You are right. But Xen is planet or moon by Pluto of our solarsystem. But xen is an original name of planet or moon “xena” or “xeno”.
xen world looks with asteroids better like we live here with solarsystem.
habitable palents like gliese or kepler, cerpore ( ?, i have readden latest time on internet. but i don’t know what is name of real different habitable planets from universum. )
But i am not shit. I force again because i have readden a lot of news by NASA / ESA. That is correct for habitable planets.
I am sorry because i fight for correct suggestion and improvement for Black Mesa Source
But i won’t hurt you - i want give same suggestion 
Please believe me!
I don’t even know what most of this means. You’ve been given the correct answer as far as we know it. This really doesn’t warrant further discussion.
Your suggestion has been duly noted. Your creative input is much appreciated.
The moon you are saying (satellite of Pluto) is very different to the Xen in Half-Life. They may have the same name but they are different.
What the hell are you smoking, boy?
I have no idea what that is (I assume it’s not actually leaked footage, if for no other reason than the gif is suspiciously square), but it’s damn cool!
I can barely understand those posts. Seriously, the grammar is a fog.
Heheh, neat. But that’d be a silly direction to take Xen. 
That’s not how source handles reflection and refraction…
I guess the scientists just called it Xen, cause they maybe didn’t know the real name of it
