Yep, That's right. This mod will be going live in about an hour, in which I'll be uploading images, and a video. While I'm at it, I'll explain some stuff.
Only one map was changed in this entire mod, which was [c1a0d], which is where you acquired the H.E.V suit. I changed it so that the H.E.V suit was gone from the start, and so that Barney wouldn't talk to you at all about being let through. Although I also screwed up the lighting in some areas, so it looks far from perfect.
As for the viewmodels, they've been changed to accommodate for the lack of an H.E.V suit. They're based on the Blue Shift viewmodels, with retextured recoloured sleeve textures. They seem to work perfectly fine on HL:Steam, although they occasionally pop in and out of existence when using New Gauge Half-Life. (But that might be a problem on my part).
Other then the viewmodels, the only model changed was the H.E.V suit, which I changed to a lab coat. Although it's next to useless since the H.E.V suit only appears about once throughout the entire game.
As for the player model, I left it unchanged. I highly recommend installing DerickFabro's Gordon labcoat player model. Just put it into the models folder of the mod, and rename it to player. The main reason I didn't put it in there was because of possible conflict about mod stealing.
c00l mod!
