Scotty

"Then why don't you crawl you're fat ass down here and do it yourself?"

- Scotty to Ross Fry, after the latter said that his job wasn't that hard

Scotty was a maintenance technician assigned to the Mars City Underground. He was under the supervision of Ross Fry. On the day of the demon invasion, Scotty was working in a vent in the Energy Stabilization Unit, trying to replace power couplings. When the Player walks through this area the first time, he can hear Scotty arguing with Fry.

Scotty and Fry are killed by an Imp during the demon invasion. When the Player returns to the Energy Stabilization Unit, Scotty's dying screams are heard coming from the vent. If the Player looks into the vent, the Imp (presumably the one responsible for killing Scotty) will crawl out and attack the Player.

Trivia

 * Scotty may be a reference to the character "Scotty" from Star Trek.
 * Killing Fry will cause Scotty to suddenly respond "Ross? Hey, what the hell's going on up there?"
