MTM-8 Robotic Loader

Safe

The MTM 8 is a robotic loader used in the Black Mesa Research Facility to handle crates and other objects, as well as other tasks.

Half-Life
It is first seen by Gordon Freeman during his tram ride to Sector C. A first one is carrying a crate, a second is about to work on a radioactive leak while the G-Man is seen on another tram.

Half-Life: Opposing Force
In the chapter Welcome to Black Mesa, Shephard finds himself above a room flooded with radioactive waste, which access is forbidden as long as the loader below is working. The Loader is blocked by stored crates that Shephard must destroy with a bullet to allow the loader to proceed and clear the access.

Behind the scenes
The model has animations no seen in-game. They include "run", "heroidle" and "herodie". It probably was to be seen destroyed at some point in the game's development, likely in a scripted sequence, as "herodie" shows it in parts after a small run.

Trivia
It bears some resemblance to the power loader seen in the film Aliens.
