Continue the incredible Half-Life 2 Storyline somewhere in the antarctic through ice lansdcapes and underground bases inspired by Half-Life and conspiracy theories like the "Dulce Underground Bases" and the "Nightmare Hall" all in the confort of a new MKVII HEV Suit.
What about custom skyboxes? Well, this is still a WIP, i'm sure you'll eventually come up with something impressive :)
Also, it's too bad this is set in the antarctic, if we were at the north pole perhaps you could work on a nightlevel with the boreal aurora :D
Like the look of this area, I can't wait to play this part. Keep up the good work Timian!
