One of the main NPC's you will encounter in Dark Skies are the Conscripts. For those of you who don't know who the Conscripts are, they are the remaining government that survived the 7-hour war and are now enslaved by the Combine. The way we plan on implementing them is that they will be your enemy until after you go through the Air Exchange, then they will help you out during the uprising at City 17.
(concept art for them will be ready shortly)
I'm pretty sure they became allies when Gordon got to the Air Exchange, which happens before the assault on the Weather Control.
Your right, I put weather control by mistake.il fix it right now
