As leader of the Conscripts, Captain Vance was to play a compromised and dangerous role protecting the facility ( airex_03040506 also features several visgroups named after Vance and a command center). And the other prototype of the story draft for the Air Exchange is that it was meant to suck the earth's atmosphere through a portal to operate dimensional turbines to generate power for other dimensions, which could possibly explain the unknown blue energy being present in the facility's main reactor. The transported air was designed to make the surrounding region breathable for Advisors at the cost of making the air highly toxic for human life, which caused most of the City 17 inhabitants to wear gas masks. One of them and the most known story draft is that the facility was supposed to replace the air with noxious, murky gases, with its main reactor powered by an unknown blue energy source, probably the storyline predecessor of the Dark Energy reactor. The Air Exchange had two debatable story changes during its development. Similar on the surface to common Earth factories, it was to be a Combine facility guarded by Combine Soldiers and Stalkers that went cycles during the chapter's development. Still, we’d have to see more before really talking about what this could and could not have been.Like the Citadel, the Depot and possibly the Weather Control, the AirEx was to be one of the many Air Exchanges spread on Earth by the Combine. The concept art as a whole is quite good, but the character designs are nowhere near as well-done as Valve’s work. The concept art includes two drawings of an Eastern European city resembling City 17 ( this one and this one), a drawing of some sort of abandoned town named “Haven”, a drawing of the interior of an apartment block, again, resembling what we’ve seen in HL2 and the Episodes, a shot of what seems to be a very different Civil Protection officer with a City 17 arm band, and a drawing featuring some sort of Overwatch Soldier, who looks almost nothing like the Overwatch Soldiers we know and love from HL2 and the Episodes.

The only information he gave is: “cancelled project”, which leads us to believe that this is Episode Four, and it was in fact in development at EA. He gives no details about the project, and it isn’t in his resume. He has just posted up 6 pieces of concept art for some sort of Half-Life project developed by EA on his Coroflot profile. Randy Humphries is a concept artist and 3D modeler.
