we showed you the first glimpse at Half-Life: Episode Three concept art

Into the Pixel art exhibit

Probability: 90%. Half-Life 2 showed the city; Episodes One and Two showed the great and green outdoors. Trekking to an icy locale like the Arctic (or Antarctic) would make for a perfect change of scenery, and would add even more mystique to uncovering buried secrets. We hope the HEV suit comes with built-in heaters, for Gordons sake.
