Other than that pretty cool if not a little silly considering there are two lab coated scientists standing around on Xen.
I had helmets on the first npc, but since the head was moving it looked silly on a couple of them. I figured since Gordon went to Xen without a helmet, why not them? Unless he did, I'm not completely sure...
How did you achieve the final scene where the camera turns off? Did you create a custom map, place an NPC there with a custom skin, and a tripod camera model there and place a optical flare effect using Adobe After Effects?
The camera was a model that came with a Camera shake swep created by Patrick Hunt. The map was plain gm_darkgrass with a Room created with Lab and PHX props. The lens flare was created with Video Copilots "Optical Flares" addon. The tripod was also created with 3 phx poles.
