You're walking around Black Mesa, until you see a mechanical thing, a Loader, painted that familiar, Black Mesa, black and orange, carrying boxes, and you just kinda, stare up at it until...

"STATE. BUSINESS."

The Loader calls out, trying to determine if you are a threat, or not. It decides you aren't, cause you don't seem threatening, at all... and you just kinda, stare at each other.
