The '''Loader''' is a robotic power loader used in the Black Mesa Research Facility.

==Overview==

Powered by a number of hydraulic joints, the Loader is a yellow WikipediaQuadrupedalism|quadruped robot that is crab-like in appearance with two pincer-like claws used to clasp onto objects. It has the text "MTM 8" and "No Entry" written on the side of its body. The Loader is seen handling crates and performing other maintenance tasks in the facility, particularly in locations with hazardous conditions. The robot acts autonomously, although it has a suspended cockpit with controls at the rear of the machine.

==Appearances==

===''Half-Life''===

Two Loaders are seen by Gordon Freeman during his Black Mesa Transit System|tram ride to Sector C along the Sector C#|Sector C Line. The first one is transporting a wooden crate, while the second prepares to work on a radioactive spill leaking from a nearby storage tank, temporarily obstructing Gordon's tram in the process.

===''Half-Life Opposing Force''===

In the chapter ''Half-Life Opposing Force storyline 2 Welcome to Black Mesa|Welcome to Black Mesa'', Adrian Shephard finds himself above a loader bay flooded with radioactive waste. Access to the room is forbidden as long as the Loader below is operating. The Loader, carrying a green metal crate, is blocked by the rest of the crates in the vicinity that Shephard must destroy. Once the obstructions are removed, the Loader proceeds along its designated path and exits, leaving behind the green crate which Shephard uses as a platform to safely cross the toxic materials.

As the elevator adjacent to this room leads up to the same section of the Sector C Line where the second Loader was witnessed in ''Half-Life'',{{IA|20000118212001/http//gamepen.com/preview/PC/08_20_1999_785_3.asp|''Half-Life Opposing Force'' - Interview|Gamepen (August 20, 1999)}} it is likely these two Loaders are one and the same. Between Freeman's and Shephard's passing through the area, the previously seen leak has since been repaired.

==Behind the scenes==
The original Loader model in ''Half-Life'' was designed, modeled, textured, and animated by Valve Corporation|Valve artist Steve Theodore.{{IA|20070513091613/http//216.39.145.248/resume.html|Steve Theodore's personal website}} It bears a resemblance to the power loader seen in the film ''WikipediaAliens (film)|Aliens''.{{IA|19991013004047/http//pc.ign.com/previews/11667.html|''Half-Life Opposing Force'' preview|IGN (May 25, 1999)}} The Loader was one of the models that Valve used at the WikipediaEuropean Computer Trade Show|European Computer Trade Show to demonstrate the flexibility of the GoldSrc|GoldSrc engine's skeletal animation system.http//bluesnews.com/articles/newellinterview.html Q&A with Valve's Managing Director Gabe Newell on Blue's News (September 13, 1998) The model had actually been created for a series of planned puzzles in the game, but these were all later cut. The player was intended to remotely control a Loader with a lever control system that would allow him to combat and defeat a Gargantua. The level art and animations for this sequence were made, but the AI was not completed.Steve Theodore on ReferencesValve_employee_emails and the Loader (February 2, 2014)

In ''Opposing Force'', Gearbox Software|Gearbox originally planned for the player to be able to commandeer the Loader as a drivable vehicle. However, as this plan failed to culminate, designer Randy Pitchford worked with level designer Rob Heironimus to create the blocked Loader puzzle featured in the finished expansion. Landon Montgomery made the animations for this sequence. This puzzle was a last minute addition and was developed in two days within the last week of the game's production.http//planetphillip.com/posts/audio-interview-with-gearbox-software Audio Interview with Gearbox Software on PlanetPhillip (November 3, 2012)

===Animations===
In ''Half-Life'', the model possesses several unused animations "run2", "freeze", "heroidle", and "herodie". The final two depict a sequence in which the machine runs forward, crashes into something, and subsequently falls apart. This act would trigger an entity called "loaderhit" which can be found in the map c2a5f in the final game.

In this level, a M2A3 Bradley|Bradley enters a FileC2a5f apc.jpg|large hangar to deploy Hazardous Environment Combat Unit|Marines by crashing through the hangar door. This event triggers two multi_managers, "loaderhit" and "loaderhit2", but none of the objects referenced by these entities exist in the map. If they were still present, this would trigger an elaborate destruction sequence in which the catwalk breaks down. It is possible that a Loader was to cause this destruction in the cut sequence. In the final game, a part of the catwalk is already destroyed before the Bradley enters.
