Yep, some more so these. Made a lot of progress in a day or so.

At this point, the map is more or less done. I could add some enemies, items, and maybe the lift to the helipad, but I don't have any snow textures for the surface (though I could just say the base is in an America desert now). There is some empty space, such as the area you can see on the right of the top screenshot. But I didn't want to just copy and paste the opposite side. I can fill the spaces with clutter if needed.

But yeah, as a project, there's not really much I can think to do. Not sure if I'll incorporate this into something else, we'll see.

One bit of trivia, the area you have to work with in Half Life is actually pretty small. The limit is about 8000 units cubed. This little area you see here, used about 2000x4000, and about 1000 units tall.

Hope you like it.
