Dark Skies is a total conversion mod that aims to recreate the original story of Half-Life 2 while keeping a fresh feel from the other mods doing the same thing. Almost every thing will be redesigned to have our own touches but still resemble Valve's old concepts. Dark Skies will contain many new enemies, new gameplay and dark and desolate levels.
Here is a new concept of the Air Exchange on the dried up ocean floor.
Cool.
Looking good :)
Nice, but just make sure to include the Airex tower as well as the reactor.
The reactor is the big thing belching toxic fumes. As for the tower, it just isn't visible at this angle, as with a lot of the AirEx facility.
