Sector E, referred to as Sector E Biodome Complex,[1] is one of the seven main Sectors of the Black Mesa Research Facility.[1]

Biodome Complex[edit]

The Biodome Complex is is a location featured in Opposing Force in the chapter Vicarious Reality. It is a large facility that contains a series of simulated environments where captured aliens and flora are kept and observed in artificial recreations of their natural habitats. Alongside these enclosures are laboratories where scientists perform studies and tests on the creatures in closer detail.

Materials Transport[edit]

See also: On A Rail

The Subsurface Materials Transport System, also simply known as the Materials Transport, is a location featured in Half-Life and Opposing Force in the chapters Power Up, On A Rail, and Friendly Fire. It is a large decommissioned underground rail system which consists of a network of train tunnels, storage areas, and offices.

Track Control[edit]

See also: Power Up

The Track Control is a location featured in Half-Life in the chapter Power Up. It serve as a control station for the rail tracks of the Materials Transport system. It consists of maintenance areas and a generator that supplies power to the rail tracks. It is possible that the area was used for the maintenance of rail carts.

High Altitude Launch Center[edit]

The High Altitude Launch Center[1] is a location featured in Half-Life in the chapter On A Rail. It consists of Silo E, a silo converted into a fully-functional satellite delivery rocket launchpad (the Satellite Rocket Loading Bay), and the Launch Control building. This is used by the Lambda Team, with the help of Gordon, to launch the satellite that later helps revert the Resonance Cascade.

Sector E Line[edit]

Sector E is connected to the Green Line of the Black Mesa Transit System.[1] Connected to the Area 9 Security Checkpoint, this Black Mesa Transit System line is located below the Sector B Line and above the Sector C Line. Its direction of travel is unknown.[2]

Sector E Subsurface Transport[edit]

Level A of this Black Mesa Transit System section can be accessed from Sector C Line, where the G-Man is first seen in Half-Life, and leads to an unnamed area where the first Shock Trooper and zombie security guards are encountered.

Behind the scenes[edit]

Riller's name in the Materials Transport, more visible after throwing explosives at it and image overbrightening.

Half-Life includes several unused signs for the Track Control and the Materials Transport. According to these textures, both locations were originally part of Sector D. There was to be a Train Hub in the Track Control, an Administration area with three levels, and Loading Bays in the Materials Transport.

The unused Materials Transport sign "c2a2a_sign2b", which says Subsurface Transport Level A, was recycled for Opposing Force, and appears in the Sector C line of the transit system. The filename prefix indicates that the sign was to appear in the second map of the chapter On A Rail.

Easter eggs[edit]

In Half-Life, Dave Riller's name, a level designer who worked on the Materials Transport levels, appears in the map c2a2c, under grates, which can be entered from a hole under the stairs. This was removed in the console ports of the game. In Opposing Force, the names S. Jones and S. Reardon appear in an office found near the Lambda Sector Transport. These are references to Gearbox employees Sean Reardon and Steven Jones.
